Almost best car prank...

A former coworker thought he was funny and would mess with my car. The first time having my wipers on and radio blaring when I start the car... Ok, ha ha, you got me, don't mess with my car again. After the 3rd or 4th time... he had some payback coming.

I got in his car and disabled the power windows, disconnected the inside door handles and the horn. He could get in, but he couldn't get out. Now, this was in the days before cell phones, so he drove around for hours trying to get someone to open one of his doors. Never touched my car again.
