The Mii Lebowski
Filmmaker Ben Moody synced up Lebowski audio with video from Nintendo Wii Bowling. Their mouths don't move much, but watching a Wii Walter chastise a Wii Dude ("Chinaman is not the preferred nomenclature") is hysterical.
The Effin' Short Lebowski
The word "fuck" or variations of it (fucking, fuckhead, fucking fucks, etc.) are spoken 281 times in The Big Lebowski. This video compiles all of them in a mere two minutes and 15 seconds. Not safe for work, Dude.
The One-Man Lebowski
Shot in what appears to be a living room, this version of a Lebowski scene features low production values and a balding, middle-aged man who looks nothing like either the Big Lebowski or the Dude. But his re-creation of the Lebowski summit is solo bliss.
The Freakin' Good Lebowski
The endless profanity in The Big Lebowski made for some bizarre cable-TV dubbing. Goodman's R-rated line "This is what happens when you fuck a stranger in the ass" is now "This is what happens when you find a stranger in the Alps."
