Ours was Hernan Cortez. But it was the trademark of one guy on the team, and the one time that Cortez was an answer, he wasn't there. He was really disappointed.
Then there were the QuizNet contests, where we'd occasionally make something up when nobody on any team knew the answer. Usually they'd all just repeat the answer we gave, and it really annoyed the moderator.
ETA: Oh yeah, and zombies should be able to run. They should shamble as their normal "walk", but also be able to run.
It's a pain that zombies are so slow, but what I do is take them to the Far East (a bit of treasure digging or fishing and the trip will pay for itself) and get the ninja to teach them to teleport. Very convenient.
