Took a basic film photography class in high school - learned how to use a darkroom, the whole nine yards. Haven't used film in a camera since (4 years now).

I also used to be able to solve a Rubik's Cube in around a minute. I can still do it, but it takes anywhere from a minute and a half to two minutes now. Still haven't found a practical application for speed-solving yet. The ladies aren't as impressed as one might think with that particular skill.
