UPDATED: Jay Leno takes swipe at Letterman: Late-night chaos continues, Conan, Kimmel, Fallon weigh in

Last night on The Jay Leno Show, the host once again addressed rumors that he was being “fired” by NBC.

Jimmy Kimmel also weighed in last night, saying that “Jay Leno and Conan O’Brien are moving in together. ” Kimmel took questions on the subject from the audience (with a little help from Carson Daly):

Kimmel also illustrated the new carving-up of the late-night pie by bringing out a pumpkin pie, cutting it to suggest audience segments for the hosts… and then eating the pie.

And Jimmy Fallon sent out a “thank you note” to NBC for “announcing that Jay Leno will be moving back to 11:30… It’ll be interesting to see how [my show] does up against the ‘perfect push-up’ infomercial.”
