Trip Wire 

Setting up a Trip Wire in Our Dorm Room.
First off, sorry for the crappy quality. This was from 2004 on a crappy camera and we turned the lights off so my roommate wouldn't see the camera. Anyway, my buddy Mickey had this great idea for pranking our annoying roommate, whom we'll call TFC. We tied an extension cord to a table and a chair right in front of TFC's door. After pounding on his door a few times, we got the reaction we were hoping for. TFC comes charging out of his door, stumbles over the trip wire, does a Fred Flintstone barefoot squealing stop, then charges at Mickey, who jumped on the bed in my room. TFC charges fist first at Mickey, who subdues him with a chokehold within about 2 seconds flat. That pissed off TFC even more and made for an even better reaction. Just so everyone knows, TFC is one of the most annoying people I've ever met and deserved everything we did to him.
