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):

Here’s the video of Twitter co-founder Biz Stone with Stephen Colbert last night on the Comedy Central cable television show.

Stone–the spokesmodel for the hot microblogging service–does very well and is even charming, even though Colbert nails the problems of the San Francisco-based Twitter cold in the lively interview.

“How would you make money?” asked Colbert, after some preliminary joking with Stone about Twitter’s 140-character limit.

When Stone went on about how Twitter planned to be a “strong, profitable, independent company,” Colbert was ready with a zinger.

“You and Pets.com.”

Still, it was semi-cute when Stone told Colbert that “if i have a son, I should name him Flint.”

Yabadaba–don’t, Biz.

(Stone’s actual first name, by the way, is Isaac.)

Here’s the video:

Stone (pictured here)–who has clearly become the chatty spokesmodel for the hot microblogging service at public events all over the place of late–is set to be a guest on Comedy Central’s “The Colbert Report.”

Stone, of course, just updated everyone about the show on Twitter and also on his blog site.

“It’s past 2am here in NYC and I’m battling email until I pass out—tomorrow, I’m on the Colbert Report! I’ll keep you posted. 9 minutes ago

Just landed at JFK with my wife, @livia (who grew up in Manhattan) — looking forward to a couple days in NYC! about 4 hours ago

Normally I’d fly @jetblue but since I’m headed to NYC to be on Colbert tomorrow night I’m flying American (flight is delayed) about 11 hours ago”

I have no doubt it will be snarktastic, especially given the bulls-eye piece Stephen Colbert’s comic twin, Jon Stewart of “The Daily Show,” did on Twitter recently, nailing the unholy media obsession with tweeting.

Until the show, which we will post later, here is a very funny video Colbert did for our 2007 D: All Things Digital conference about the Internet, when Viacom (VIA) head Philippe Dauman was interviewed onstage, so Biz can better prepare for his comic grilling, um, interview.

And Stewart’s Twitter-bashing video is also below.

At its EconCeleb conference in Hollywood today, ContentNext released its list of the most influential and innovative online celebrities today.

It is an interesting and varied list that includes everyone from powerhouse Oprah (pictured here, of course!) to the bisexual sprite, Tila Tequila.

The list, in ascending order:

10. Martha Stewart (she is actually a closet geek)

9. Tila Tequila (vile, but in a good way)

8. Peter Gabriel (a longtime Web pioneer in the digital music space)

7. Radiohead (innovative band pushing Web distribution boundaries)

6. Stephen Colbert (funny online and off)

5. 50 Cent (the urban rap artist as nerd)

4. Oprah Winfrey (um, she’s runs the real world and could run the Internet if she felt like it)

3. Ashton Kutcher (not just a pretty face, but one who gets the power of viral marketing)

2. Will.i.am (for that Barack Obama mashup video alone)

1. Will Ferrell, Chris Henchy & Adam McKay (FunnyOrDie.com might not make money, but it is very funny)

Before I interviewed Viacom CEO Philippe Dauman, the crowd at D5 got to see a very funny video Comedy Central star Stephen Colbert did as an intro for his boss, whom he dubbed the “Dough Man.”

The Dauman interview took place the morning of May 31, 2007 at D: All Things Digital, the annual tech and media conference that Walt Mossberg and I host. The next conference takes place in late May 2008.

I dare you not to laugh when Colbert puts a piece of cable into a piece of cake and starts sucking.

Here’s the video:

It’s all part of the three-ring circus that the copyright-infringement lawsuit between the Google-owned video-sharing unit and media giant Viacom, which owns Comedy Central, where “The Daily Show With Jon Stewart” and “The Colbert Report” air, will likely become.

Viacom is suing Google for $1 billion for allegedly letting stolen content proliferate on its service.

Viacom’s imperious chairman and main shareholder Sumner Redstone is also on the Google witness list, a deposition that will likely be comical in its own unintended way. But we want a front-row seat for Stewart and Colbert, who probably like how popular their material is on the Web.

Now, thankfully, Viacom is providing a lot of embedded clips from both shows and I am guessing really wants to settle this and get on with the job of monetizing its video trove (doubtlessly, with Google’s help).

Google, on the other hand, is ridiculously stubborn enough not to settle, even though it probably should, as its execs seem to want a solid decision on the issue, even if it turns out badly for the company.

In any case, video flourishes on the Internet, despite all the rancor. And it is even funny.

Here’s a recent example of an embeddable Stewart video on the departure of Republican political impresario Karl Rove:

And here’s a very funny intro video Colbert did that ran before an onstage interview I did with Viacom CEO Philippe Dauman at D5 (by the way, it got ripped into YouTube in about 14 seconds after we put it up on our Web site on May 31):
