Too bad that they never used Kari on any episodes/segments about why we are ticklish or that one segment(from a pre-Kari Bryon era episode) about why we have body and foot odor one(that had one of the guys[from the past episodes] as that subject).
In two episodes we saw that she's ticklish. The "Cold Feet" one, putting the sensors on drove her nuts. And the one about the tin man from Wizard of Oz, We saw a ticklish reaction when the brushed the make up on.
And she gets tickled in the germs episode where they use glow in the dark paint to show how much germs spread. She is one of the people who is very carefull about not getting germs so Adam tries to give her a hug and she just throws her hands up in a "whoops, nope don't hug me" and he gives her a quick tickle. No idea about the name or timestamp though.
