Watch David Letterman Say Goodbye on His Final 'Late Show'

After 22 seasons, 4,262 episodes, and tens of thousands of celebrity guests, it's no surprise David Letterman's departure from The Late Show is hitting a lot of stars pretty hard.

Actors, comics and musicians have been taking to Twitter, Instagram and Facebook all day sharing congratulations as well as memories from their time on Dave's show.

[Stars and scenes from the May 20 finale:]

Some even shared stories of how Dave influenced their lives and careers. Parks and Recreation star Adam Scott shared, "A good 80% of why I wanted to do any of this was to one day sit on Letterman's couch."

Some stars didn't want to accept the reality of the situation. Jennifer Lawrence posted a photo begging Dave not to leave.

Even Dave's fellow late-night hosts (even those he's competed with) encouraged their viewers not to miss his last episode.

Many celebs just wanted to make it known that they appreciated all the laughs and good times from Dave's long, groundbreaking career in late-night television.

My last HA HA with Dave tonight. #ThanksDave

This truly is the end of an era, and it's going to be interesting to see how his successor, Stephen Colbert, does behind the Late Show desk.
