I was listening to this clip of Larry David and Jason Alexander on Fallon and his laughter is so obviously fake. I know that late night hosts are supposed to be affable, but even so - I never saw Letterman or Conan bang on their desks like retards every fucking time the guest attempts a joke. I'd call it sociopathic but I feel like an actual sociopath could feign human laughter better than Fallon does.

PS - re-read the title carefully for a big laugh
