The Dude

 So... my buddy Bernie Glassman says to me one day, "Did you know that the Dude in The Big Lebowski is considered by many Buddhists to be a Zen master!"

I said, "What the fuck are you talkin' 'bout, man?"

He said, "Oh yeah."

I said, "You gotta be kidding. We never talked about Zen or Buddhism while we were making Lebowski. The brothers (Joel and Ethan Coen) never said anything about that."

"Yeah," laughed Bernie, "just look at their name - the Koan brothers."
