Best/Worst joke I've played was when I wheeled down the driver's side window on a friend's car, smashed some glass on the pavement next to his car, and put a big rock by the front tire. I could see him staring at this mess from an office window. Sticking his head inside the open window and everything.

Yes I know it would seem odd that the glass and rock were outside the car, but I sure scared him for a few minutes.

Served him right for forwarding all of his incoherent callers to me that day. :joker:
