I rented Eraserhead years and years and years ago, when I was in high school, and immediately became a David Lynch fan. It is probably one of the strangest movies ever made, and I'm not even sure how to describe its humor. Everybody in the movie acts like they're either permanently stoned, or lacking vital parts of their brain. I think I'll try to find the DVD, or maybe Google it in hopes of finding out what it really was about. The line
"They're not sure if it is a baby yet..." and the long ride in the elevator remain burned into my mind to this day.
Besides Eraserhead, I'll vote for "This Is Spinal Tap" and pretty much any Monty Python movie. The interrogation scene in Something About Mary also had me in stitches.
