They get mildly funny dudes to make lukewarm jokes and everyone is obsessed with it. Conan was funny and Letterman had his moments but the rest of them are both wack and beloved.

Then when someone who's actually funny is there they seem to get jealous and nervous. I saw Jay Leno almost kill himself cause Louis CK was making jokes about him and Jimmy Fallon almost have a heart attack when Bill Burr said Hikaru goes to Bilderberg meetings
