If you're a late night talk show aficionado, you probably know all about the Jay Leno and Conan O'Brien debauchery that resulted in Conan O'Brien moving from NBC to TBS.  I blame it on NBC for moving the scheduling around and catering only to Leno's future. I had somehow missed this 'Leno bashing' interview of Conan on Dave's show following the whole fiasco.

Below is an interview with Conan O'Brien on David Letterman in which the two take several jabs at Leno. It's quite clear neither of the late night talk show hosts have much affinity for their counterpart Leno. Letterman and Leno once were friends and it's an interesting contrast to watch and early 1990's interview between David Letterman and Jay Leno. Do you think it's just a lot of show are is there real animosity?
