Bill Murray Improv Amazingness

The only actor with his own tag on this site is known for pulling comedy out of thin air. But he doesn't just have fun when he's on the show of his buddy, David Letterman. No, he gets playful with Conan O'Brien as well - and with the staff, no less.

His part of the clip is only about a minute and a half long, but damn if Mr. Murray doesn't make the most of it.
