Dave Chappelle went on the Late Show With David Letterman last night for one of his only interviews in years (there was the one with a Minneapolis television station, and another on San Francisco radio). He talked again about why he abandoned Chappelle's Show, what exactly he gave up when he did and whether he regrets doing so.

Last night official Oprah's Favorite Things actress Lindsay Lohan's US sobriety tour swept into Letterman for an awkward but earnest segment about personal growth and a guy named Meditation Bob.

Jason Sudeikis announced tonight on Letterman that he's leaving SNL. He's the third male cast member to leave the show since last season, following Bill Hader and Fred Armisen.

Joe Halderman, who is accused of attempting to extort $2 million out of David Letterman, ate lunch with a veteran Nashville homicide detective just days before he left a note demanding $2 million in Letterman's car.

It turns out the man accused of trying to extort $2 million from David Letterman for having "creepy" sex with his own staff knew from creepy. The brawling, hard-drinking 48 Hours producer was reportedly known for his own intra-office liaisons.

The CBS newsman accused of blackmailing Letterman has pleaded not guilty to attempted grand larceny by way of extortion. Here's the barebones indictment, which includes no new information. Bail has been set at $200,000.

In addition to her other duties around the set, assistant-in-question Stephanie Birkitt was a frequent on air presence on the Late Show. Although the CBS authorities seem to be rapidly scrubbing the web of Birkitt's clips, we've rounded up a couple of her greatest moments joshing around with the boss.

The CNN founder is out promoting his new autobiography, which gives him a chance to go on and on and on about his pet grudge, the scalawags at Time Warner who blew up his fortune by merging with AOL. Dude, it was only seven billion. Let it go! Here he is on David Letterman talking about how CNN sucks these days, without him, Ted Turner, around.
