Bill Murray showed up on David Letterman last night, to celebrate the 20th anniversary of 'The Late Show' (of which, Murray was the first guest). Naturally, he celebrated it in style; you'll want to see this.

Bill Murray made like Liberace for his appearance, arriving in a classy car, poodle in hand. After chatting with Dave for a while, he breaks out a pickaxe and set to looking for a time capsule that he has apparently buried underneath the chair. And then sings Whitney Houston. Yes, it's as weird as it sounds.

And wait until you see what's in Bill's mystery box. Take that, J.J. Abrams!
