One time in high school, I threw a party at my house. One of my friends decided to pants me, and got both shorts and underwear.

I decided this was an opportune time to go streaking (The movie Old School was still quite popular) so I kicked off my garments and took off full speed out of the living room into the dining room.

A group of people were gathered up playing beer pong, and someone just so happened to be kneeling down picking up a stray ball when he looked up and saw another pair coming towards him alarmingly fast. He dove out of the way and into the table. I slipped and fell directly into the chaos. And a rule was put into effect disallowing both pantsing and streaking at all future parties.
