I just finished watching the last 10 minutes of Are You Smarter Than a Fifth Grader. And seriously, it has to be rigged.
Either the contestants are actors or they're prepped for the show. I can't believe that someone wouldn't know how many legs a mosquito has, and would spend five minutes fluffing around pretending she doesn't know.
So either she's dumb for not knowing, or I'm dumb for watching.
