I personally like Fighting Zombies better, but hey, robots work too!

Zombies don't really fight, though. They just sort of amble along until they find something living and then rip it apart mindlessly, eating the fun fleshy bits. Neat, but not exactly awe-inspiring.

One other suggestion I've heard is having our mascot be a big orange and blue dot. Guaranteed not to offend anyone, and is a part of "dot com".

I can vouch for the fact that robots and corn have much more to do with our school than native americans, though. :)
