I'm sure the statue of limitations is up so I free to share this story. A long time ago I had someone at work that took hazing the new guy way to far. I got even one day when I noticed that he left his car unlocked by mistake. I climbed in and emptied a half can of OC spray into his heater vents and then turned the blower on full blast so that when he started up his car...yep, a face full of OC.
Oddly enough, he hated me for the rest of the time I worked there, but guess what? He never messed with me again after that day.
