David Letterman has done it all.

Interviewed the biggest names on the globe, thrown things off the roof, you know, everything.

One thing he hasn't done is retired, until now.

He just announced that when his current contract runs out in 2015 he is stepping down.

David has been doing late night longer than anyone, including Johnny Carson's long run on The Tonight Show.

Maybe it's time to relax, but we still will long for his dry wit every night.

Here's Dave making the announcement.
