Are you serious about the farting part? What was the outcome?If their ratings ever dip too low all they have to do is have Kari go topless on an episode. They can blur out her nips, it won't matter. Now to find an experiment to justify that. I'm sure they can come up with something.
I mean hey, they did the one where they jammed microphones in her pants to see "if women fart". So the show isn't 100% class.
And maybe they can do an experiment to see if cold weather causes her nipples to harden.
