The first time I got dental x-rays as a kid really freaked me out. The lead smock they draped over me was really heavy and made it hard to breathe. Then everyone else left the room while this mechanical arm with a loud buzzing tube aimed at me slowly moved around my head. I like the new version much better where the buzz-o-matic only shoots you for a second instead of drenching you for the better part of a half hour.
Also, Biff art for your wall!
