David Letterman

When Peyton Manning appeared on David Letterman's farewell show, all he got to say was "Dave, you are to comedy what I am to ... comedy." Now, we know what he really thinks about the retiring late night television host.

There were no scheduled guests on the final episode of The Late Show With David Letterman (minus The Foo Fighters, who closed out the night with a performance of “Everlong”), but that didn’t mean that a few of Letterman’s old friends didn’t stop by to say goodbye one last time. Some of the funniest people alive all came together to present one final Top Ten list, Things I've Always Wanted to Say To Dave.

Bob Dylan made his final appearance on 'Late Show With David Letterman' on May 19, 2015.

T-minus one week and counting until the very last Late Show with David Letterman and the tributes are coming faster and faster, and sadder and sadder. I hope on the last installment of Stupid Pet Tricks one of the tricks is a shih tzu shedding a single tear for the end of this venerable late-night franchise, which comes to a close on May 20. It’s only fitting.

He had, of course, previously been a regular musical guest on the 'Late Show.'

‘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.

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?

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

"Summertime! Summertime, people!" Sure, Bruce Willis. We can blame this on it being the summertime. The actor hit 'The Late Show' last night to ... honestly, we don't even know, but eventually it devolved into Willis eating corn on the cob harmonica-style and getting absolutely covered in melted butter. It seems that Willis is a huge fan of corn -- can't get enough of it! -- and he was eager to share some corn-centric life hacks with host David Letterman.
