David Letterman

Well...not really. But, David Letterman couldn't help but bust Oscar Isaac's chops.

‘The Colbert Report’ has already said its goodbyes, while David Letterman will hang onto the ‘Late Show’ until May, so when does Stephen Colbert finally take the desk, and begin our new era of ‘Late Show with Stephen Colbert?’ Find out, as CBS has released the official start date, and teased some specials from Letterman himself!

Stephen Colbert has already begun making the final rounds of ‘The Colbert Report’ in preparation for his new CBS ‘Late Show’ hosting gig, but don’t expect David Letterman to vacate the chair just yet. The longest-running late-night host has officially set a departure date for May 2015, bringing an end to ‘The Late Show with David Letterman’ as we know it.

Ben Stiller has accomplished a lot in his life -- this is the guy who created 'Zoolander,' after all -- but his dearest memory might just be a very unexpected one: that time he survived a hot air balloon ride. Said ride wasn't conceived of as a daredevil experiment, it was actually a fun part of a Stiller family vacation in Italy. It was supposed to be a good experience!

Often, particularly colorful characters take to the various late shows to flex the full range of their unique spirit, just for funsies. Joaquin Phoenix looked to be going down that precise path on last night's 'Late Show,' actively imitating himself learning yoga, calling his more personal bits "Julio Igelasias," and just generally having a good time. Host David Letterman looked nervous, but Phoenix looked relaxed, and that might be why Phoenix's good-time appearance took a serious turn when the 'Inherent Vice' star announced his engagement on air.

Here is a brief list of things that happened during Jennifer Lawrence's appearance on 'The Late Show' last night: she sang with host David Letterman, the duo discussed tummy troubles, they chatted about bowling, they both totally biffed introducing a clip, Lawrence begged Letterman to not retire, they walked out during a live taping, and then Lawrence took over the entire show.

Although we understand that 'The Late Show' will be getting a bit of a makeover when long-time host David Letterman exits later this year, and while we're extremely excited that Stephen Colbert is taking over the post, we still have a teensy idea: maybe Bill Murray could host it? Or just appear on every single episode? Does Colbert need a sidekick? He has to, right?

When you've been in Hollywood as long as Michael Keaton has, you've probably seen a lot of weird stuff created by fans -- a lot of signs and strange drawings and maybe a wacky letter here and there -- and although that sounds a little off-putting, Keaton is into it. At least, he's into it when your fan art is good, as was the case with a 'Beetlejuice' tattoo he spotted during a late night shoot on his upcoming 'Birdman.'

David Letterman finds out that the CBS Orchestra is not allowed to play any Eagles songs.

The rules are simple (in fact, they're pretty much contained within the game's actual name) when it comes to Billy Eichner's 'Celebrity Child or Kentucky Derby Winner?' The 'Billy on the Street' host will name a particular name, and then you need to guess if it belongs to the child of a celebrity or a race-winning pony. Along the way, the loud-mouthed host will use his trademark screaming ability to drive things right along, and if you can get through the tricky trivia and the ear-splitting growl, you can win a dollar for each correct answer.

Acid-tongued comedienne Joan Rivers recently stirred up a little bit of trouble when she walked out of an on-air interview after taking issue with the supposedly "negative" host (who was asking Rivers - who makes her bread and butter by making fun of people - about the negativity in her act and her latest book)...

Oftentimes when stars film new features in exotic locations, they'll spend the majority of their press tour talking about how much the new place changed them and their perspectives and their very souls. That didn't happen to Adam Sandler. The 'Blended' star hit 'The Late Show' last night, and although he quite admirably tried to convince host David Letterman that filming his new comedy with Drew B
