David Letterman announced on Thursday that he would retire in 2015, sending the comedic world in a frenzy.
The late night host debuted in 1982 with Late Night on NBC, then left in 1992 for Late Show on CBS, which debuted a year later.
Letterman's departure follows Jay Leno's from Tonight Show -- a spot that Letterman was once intended for -- which has since been taken over by Jimmy Fallon. This left most of us wondering who will claim the latest empty chair in late night comedy.
Though Letterman won't be leaving Late Show until 2015, Twitter is already speculating about the next host. Could it be Louis C.K.? Grumpy Cat? Guy Fieri?
One thing's for sure: The Internet has not failed to respond with both enlightening and absolutely ridiculous suggestions.
