My favorite episodes are where they're testing the prowess of some legendary athlete or fighter, and they, being two out of shape nerds, would try the feat, be unable to do it, and be like "MYTH BUSTED!". I was glad to see when they called in an actual master of ninjitsu to test if a ninja can catch arrows, after they themselves were unable to even get close to catching one. That ninja actually did it too! Snatched some arrows right out of the air.
