David Letterman Gets an Awesome Simpsons Couch Gag [VIDEO]

The Simpsons have done over 500 episodes and they just came out with an awesome couch gag for another icon.

The Simpsons have been around as long as I have been alive, but as it turns out Late Night with David Letterman has been around longer. It started in 1982, but for some reason I thought it started in the 90's. Well David Letterman announced he will be retiring in 2015.

Of all the late night hosts around, I am probably the biggest fan of Conan. Jimmy Kimmel is starting to come in as a close second though. I never watched Late Night with David Letterman religiously, but you have got to give the guy some credit for being on television for over thirty years.
