There's a great piece up at Cracked on the Five Superpowers You Didn't Know Your Body Was Hiding From You.
Sample paragraph: "We're kind of pissed that we can't seem to just summon the super strength at will. Wouldn't that mugger have been surprised if you had thrown him across the street into a plate glass window? But we suppose if science found a way, the muggers would know how to do it, too. Man, that would make for some awesome fights though."
Sounds like another instant classic.
