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”):

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):

Except JibJab actually asked for and got permission from Joel for the use of the song for its parody. (Props for that, I say!)

Techwise, the review of 2007 includes, the Wii, Facebook’s Mark Zuckerberg, SuperPokes and his Digital Holiness Steve Jobs of Apple and the instrument of his glory, the iPhone.

In any case, we still love “Bubble,” but here is the JibJab’s offering, which was shown on the still-writerless “Tonight Show” last night on its first night back after the writers’ strike shut it down. It is the 11th time that the Venice, Calif.-based online video-maker has appeared on the show.
