David Letterman finished his 33-year career in late-night television Wednesday with a star-studded farewell show that included four presidents and a Top Ten with one-liners from Steve Martin, Tina Fey and others:

His finale, the last of 6,028 broadcasts on CBS and NBC, drew the show’s highest ratings in 10 years, and it also touched off an outpouring of thank-yous and other reaction on Twitter. Here is a sampling:

I remember being 11 & staying up late to see who was playing on @Letterman each night. Discovered so many great artists that way #ThanksDave

Tip of the hat to @Letterman … A living legend going out on top. Will never get sick of your humour & genius #ThanksDave #33Years

A good 80% of why I wanted to do any of this was to one day sit on Letterman’s couch.

This is a contrarian opinion but I love old Letterman more than young Letterman

Watching last eps of Letterman – always a fan, never a guest- wish him the best. Btw Stephen Colbert @StephenAtHome you’re a handsome man.
