Not a movie but definitely random. A scene from the original must see TV show - Twin Peaks [video=youtube;XjeRCsoufII]http://www.youtube.com/watch?v=XjeRCsoufII[/video]
Actually I thought this was that opening scene in the Frenchman's house. There are so many great scenes in that movie. The Bear Jew!
The entire sequence in Planes, Trains, and Automobiles where Jon Candy is driving, playing pretend instruments, gets his arms stuck behind the seat, drives on the wrong side of the road between two semis, and turns into the devil.
