Mel Brooks FFA

Every Mel Brooks protagonist meets up in the middle of a totally unknown city.

R1: Straight fistfight, no weapons, no prep. R2: Fight with weapon of choice (if they don't have a weapon, think of an object that character uses a lot. For example, Leo Bloom from The Producers would probably use a cane or umbrella or some show prop). No prep R3: Weapons, one day of prep

Bonus: Which protagonist would do the best in a different one's movie? Bonus 2: They all get their sidekicks. How does each round turn out now?
