In this ruthlessly funny video–especially for such a sweet-looking young lady–singer Taylor Swift manages to ice pretty much everyone who ever dissed her.

And Kanye West’s attention-grabbing antics at the MTV Video Music Awards in September are not the only ones getting a musical smackdown from the 19-year-old, who won the Country Music Association’s entertainer of the year award last night.

In her opening on a recent “Saturday Night Live,” the NBC television comedy show, which she hosted, Swift strummed a guitar and sang “Monologue Song (La La La).”

My favorite line, which I was completely not expecting: “I like writing songs about douche bags who cheat on me.”

Sing it, sister.

Here’s the video:

Hollywood is selling the end times hard this week with the opening of “2012,” a blockbuster-style movie about the last days of the world for humanity.

Apparently, we were warned!

It’s based on junk theories about how the 5,125-year-long Mayan Long Count calendar ends on Dec. 21, 2012, which can only mean that so goes the universe.

Why someone would cite this as proof that a massive cataclysmic event is coming is somewhat amusing–maybe the Mayans just ran out of stone to chisel?–although it makes for a pretty awesome trailer for the movie, which stars John Cusack and a battleship falling on top of the White House.

The movie opens Friday, with tons of marketing and advertising online and off and a Web site with the cheeky moniker, www.whowillsurvive2012.

So, until the apocalypse, enjoy a video of the trailer, as well as the original teaser:

In it, Dwayne “The Rock” Johnson does to some politicians just what a lot of us would like to do.

Here’s the SNL video and below it, the original one from March:

It looks like Secretary of State Hillary Clinton will have her hands full with pretty dicey nuclear and terrorism issues in North Korea and Pakistan this week, but she managed to find time last week to try her diplomatic hand at working out the comic state of emergency between late-night television talk show host Conan O’Brien and Newark Mayor Cory Booker.

It started when O’Brien joked on “The Tonight Show”: “The mayor of Newark, New Jersey, wants to set up a citywide program to improve residents’ health. The health-care program would consist of a bus ticket out of Newark.”

As a counter-joke, Booker went to YouTube to make his comedy case several times via video messages, including one barring O’Brien from flying out of Liberty International Airport in Newark.

O’Brien whacked back with some good gibes, until Clinton stepped in this week in a spoof.

Maybe she deserves the Nobel Peace Prize?

This time it is tiny Cory Elliott, getting down with a diaper at 13 months old:

Of course, the video features her in a spoof of the silly action movie, although this one is much more entertaining than the real thing.

Here’s the video:

Since it was tacked onto the slasher movie, “Sorority Row,” which opened this weekend, many have been posting the brand new trailer for “New Moon.”

The second installment of the “Twilight” vampire series debuts Nov. 20, natch!

And, actually, while the first film left me in a mild stupor–BoomTown is so not the demographic for the film–this one looks pretty good because it seems chock full of the Olympic broodiness of Kristen Stewart (who is also filming a biopic about Joan Jett, which completely redeems her in my book).

Here’s one of the many video trailers, one of which already had 2,732 comments on Google (GOOG) video site YouTube since it was posted just yesterday, most of which are text versions of teen girls screaming:

And here are the first two trailers, released earlier this summer:

Suddenly, it seems the AMC original series, “Mad Men,” is having its “Sopranos” moment–with its stars all over the media, its fans more obsessive than ever and its ratings doubled in the third season.

And, just today, the potboiler television show about a 1960s advertising agency in New York was renewed for a fourth season by AMC, which is owned by Cablevision Systems (CVC).

So, of course, there are also spoofs galore online too, some pretty elaborate, such as this one with a gender switcheroo.

Fascinatingly, it still works.

Here’s the video:

Here is a slick video about social media that looks at its impact and quick influence, all of which is true, although it does manage to leave out the very pertinent question of whether or not it makes any money or not (because most of it does not yet, of course).

It begins by asking: “Is Social Media a Fad?”

More like a financial dud so far–but, in any case, it is a very fun watch. Created by Socialnomics, a blog by Erik Qualman covering social media, it is also a book that is now coming out.

While I really like the word Socialnomics, I sure wish there was some.

Here’s the video:

Here’s a new video that has been making the rounds recently featuring “Roller Babies,” which is essentially a computer-generated bunch of babies on skates doing a rap number.

It’s a commercial for Evian Water, but BoomTown laughs every time I look at it anyway–probably because it reminds me of the most famous of all viral videos on the Internet.

I speak, of course, of the dancing baby from the television show, “Ally McBeal.”

Debuting in 1997, doing a bizarre boogie to “Hooked on a Feeling,” better known as the “Ooga-Chaka” song, the innovative video was an instant hit and is one of the first and best examples of the Web’s powerful virality.

I still heart that creepy little virtual nipper.

In a genius pairing of subject and artist, here is the best online viral video this week from Conan O’Brien’s “Tonight Show,” featuring actor William Shatner reciting outgoing Alaska Gov. Sarah Palin’s recent farewell speech verbatim.

You simply can’t make this stuff up.

Done in Shatner’s perfect Captain James T. Kirk/”Rocket Man”-style, here is the video from NBC (as well as Shatner interpreting the Elton John-Bernie Taupin hit song, and also my favorite impression of Palin by Tina Fey on “Saturday Night Live”):

In April, DJ Steve Porter remixed the most excellent advertising infomercial–featuring television pitchman Vince Shlomi (pictured here) for the Slap Chop, an entertaining slasher of all foods–into a rap music video.

It has now garnered 3.8 million views on YouTube, as well as now officially becoming an infomercial itself.

Here’s the online viral video, along with another Porter did a month later for the legendary ShamWow.

JamWow:

Why can’t BoomTown stop watching the dopey machinations of the boys of “Entourage”?

Because, it’s always more of the same on the Time Warner (TWX) cable channel’s HBO show, which is oddly comforting.

And it’s a revelation that College Humor mocks perfectly in a very funny online video called “Every Week on Entourage.”

“So many twists and turns, you’ll forget they’ve been using the same formula for five seasons,” explains the humor site, which is proof that the truth is funnier than fiction.

Here is the video evidence (and don’t miss Vince as a tranny!):

Here is the latest video from the fine folks at JibJab Media, whose online political satires were among the first viral ones on the Web.

Titled “He’s Barack Obama,” it premiered tonight in front of the President at the 65th Radio and Television Correspondents Dinner in Washington, D.C.

The two-minute Obama video–which you can see below (with a little JibJab promo at the end)–is being launched in conjunction with JibJab’s Facebook Connect integration, so all comments on the video will run through the social-networking site’s platform.

Here’s the video:

And here’s JibJab’s press release on the video:

JIBJAB ROCKS OBAMA

JibJab assembles all-star rock band and premiers latest video with President in attendance at the 65th Annual Radio and Television Correspondents Dinner.

WASHINGTON, DC–June 19, 2009–JibJab, a leader in digital greetings and online entertainment, premiered its first satire of the Obama administration this evening at the 65th Annual Radio and Television Correspondents Dinner with the President himself in attendance.

The 2-minute musical video, entitled “He’s Barack Obama,” features the 44th US President in a super hero suit battling the challenges of our times to a heavy metal rendition of the American Civil War song, “When Johnny Comes Marching Home.”

He’ll use his super powers to win in Iraq,
Then kung-fu chop the Taliban! Ka-chow! Ka-cha!
Our image in the world he’ll mend,
Then make the Jews and Arabs friends!
He’s Barack Obama,
He’s come to save the day!

In a departure from their banjo-centric musicals of the Bush era, JibJab assembled an all-star rock band to perform “He’s Barack Obama.” Foo Fighters’ Chris Shiflet and Taylor Hawkins were joined by Chris Chaney, Jane’s Addiction, Roger Joseph Manning Jr., Jellyfish and Beck, and Jess Harnell, renowned television and film voice actor, under the direction of composer, John Frizzell, whose film scoring credits include “Office Space” and “Beavis & Butthead Do America.”

The video’s animation style also represents a radical departure from past JibJab productions, replacing simple collage animation with a combination of frame-by-frame character animation and live action video.

“With a new President came the opportunity to push into new creative territory,” said JibJab co-founder and Head Art Guy, Evan Spiridellis. “Our goal was to push the quality of made-for-the-web entertainment farther than anyone has ever pushed it before and we hope our audience enjoys it.”

The video can be seen for free at http://JibJab.com.

This is the second time JibJab has premiered a video for a sitting U.S. President. In 2007, the company released a satire of the news media entitled “What We Call the News” for George W. Bush at the Radio and Television Correspondents Dinner.

“We live in an incredible time when creators can get their work out to a mass audience without gatekeepers,” said JibJab co-founder and CEO Guy, Gregg Spiridellis. “When we started the company 10 years ago, we couldn’t have dreamed that we’d have the incredible honor of entertaining two sitting U.S. Presidents. God bless the Interweb.”

Even if it never makes any money, Twitter certainly does provide fabulous material for television spoofs.

So far, Jon Stewart and Stephen Colbert have done several funny bits on Comedy Central, deftly mocking the microblogging service.

And now, Conan O’Brien is doubling down with two skits so far dubbed “Twitter TRACKER” on GE (GE) unit NBC’s “The Tonight Show.”

In them, a loudmouthed voice delivers pointless celebrity tweets as a flock of blue cartoon Twitter birdies is murdered in various ingenious ways.

What’s not to like?

O’Brien, who is nicknamed CoCo by the Twitter TRACKER bully, hardly needs to work hard to make fun of real tweets like Ashton Kutcher’s mundanities, such as “Going to the grocery store need some fixins for a salad.”

There is also, of course, a snark-laced Web site and a Twitter page, so it looks like this Tweet-beatdown might just go on and on.

It should, if only for terms like: “Schprechen sie Tweetenshlize!”

Here are the online spoof videos so far (and click here to see the full interview with the Twitter co-founders Biz Stone and Evan Williams onstage at the D7 conference):
