I have a boring story about it: I've seen about 1/3 of the movie. we watched in college solely to see the famous lesbo sex scene. the DVD had a glitch, or maybe a feature (?) that wouldn't let you skip scenes or FF. we inadvertently stopped it about 1/3 of the way in and when we discovered we couldn't skip all the random, meandering scenes we just saw, and at least skip back to where we were we voted to watch something else. never saw the sex scene or the rest of the movie.
only other David Lynch movie I've seen was Eraserhead, which is... horrifying.
not really a fan of his stuff, which seems to be "weird for weirdness sake" to me. it does make for some iconic scenes and quotes though.
