Fellow evening talk show hosts were among the first to say "#ThanksDave."
It's absolutely absurd to thank David Letterman for all he's done in a tweet. But that's the world we live in now. #ThanksDave— Conan O'Brien (@ConanOBrien) May 21, 2015
A diverse list of celebrities, public figures and even sports teams watched the show and thanked Letterman for his 33 years of late-night laughs.
Thanks David Letterman for all the years of great entertainment on your program! You set me up perfectly, every time! #DavidLetterman— Jon Lovitz (@realjonlovitz) May 20, 2015
We'll all miss you, Dave. it's been a great ride. Now I can start watching Johnny Carson re-runs!— Don Rickles (@DonRickles) May 12, 2015
Any other east coast 30 something's getting a little emo on the couch right now. It's just dust....dusty in here.... #ThanksDave— josh groban (@joshgroban) May 21, 2015
