Conan Obrien Im With CocoDavid Letterman does a great impersonation of Jay “Big Jaw” Leno while discussing the NBC Tonight Show debacle.   While Conan O’Brien stands by his claim he will not do the Tonight Show if it is bumped into the next day after midnight, it seems like Jay Leno is set to ruin another late night show.

It wasn’t enough he muscled in the Tonight Show years ago while Johnny Carson and David Letterman were left wondering what happened.  Jay had to go and take back the time slot from Conan.

Check out the video below of David Letterman making fun of Jay Leno and also check out this 1992 New York Times article about how Jay Leno reacts when NBC threatens to push his show back to 12:35 after it gets low ratings.
