I had a running "feud" with a friend in college where one of us would wind up causing the other to be naked in embarrassing situations. We went on a trip with a school club to a large conference where we stayed over a weekend, guys and girls. We had a break and all went to enjoy the indoor pool at the hotel. While we were in the pool, I "pansted" him with a lot of people around. He was only exposed for a few seconds before he jerked his trunks back up.
We had a dinner that night, so I decided to go shower early so there would be time for everyone to get ready. As I'm in the shower, I hear the door to the room open, and then the door to the bathroom. He had recruited another guy, and three girls followed along. They drug me out of the shower and tossed me out into the hallway for. good 10 minutes. I just sat down and leaned against the door with my knees pulled up, which everyone who walked by found very amusing.
They realized that this wasn't being embarrassing enough since I wasn't really showing anything, so they came out and grabbed me by the arms and ran me up and down the hallway, and then for good measure we stood in front of the elevator until a group of people got off who started giggling. I was surprised no one called the front desk, but everyone on the floor were other college students, so no one really cared. By that point it wasn't even really embarrassing any more, so we went back to the room and I surprised them all by hanging out naked until it was time to get dressed for the dinner.
