LOL, that's funny. I had a similar prank played on me years ago by some of my co-workers. One of them climbed under my van, took a 24" zip tie and wrapped it around my driveshaft leaving the long end hanging. When I went to leave I heard "WHAP, WHAP, WHAP" on coming from under my van when I pulled out. So I've got the door open and my head hanging down, pulling forward and backing up trying to figure out what the hell is wrong with my van.

Then I see them all standing on the edge of the parking lot dying laughing! Funny now, not so funny then.......
