Muwhaha, this thread was the best idea we've ever had on IM Jim, Lol.
Okay so here's my addition:
Cordless Drill
Laptop
Camera, well come on, you gotta have pics of your bot in action.
Anything to make your hair a different color. (Especially Blue!)
Playstation 2, GameCube, XBox and/or any other videogame platform.
Bathing suit for the pool side.
Uber-cool Saftey glasses.
Portable CD player with all your favorite CDs for the bus ride.
Stereo for room parties, I mean... Room Parties.
Cough Drops, for when you begin to lose your voice by thursday night.
Twizlers!, the (un)official busride snack of FIRST, or at least Cutting Edge.
Well I'll stop there for now. Every one should add!
