Walter Sobchak: Dude, this is a league game, this determines who enters the next round robin. Am I wrong? Am I wrong?

Walter Sobchak: Smokey, my friend, you are entering a world of pain.
The Dude: Walter...
Walter Sobchak: You mark that frame an 8, and you're entering a world of pain.
Smokey: I'm not...
Walter Sobchak: A world of pain.

Mark it 8 with Jimmie Dale Gilmore. Not only did he play Smokey in one of the greatest movies of all time, but also he is an incredible Texas musical talent.
