Geez, I remember this girl from yeeears ago, where she fed my long hair fetish during the early days of Youtube. Kinda a blast from the past. Anyways, the video and confession you're looking for is here:

And for those of you who cant watch it (or can't stand her voice...), heres a transcription of the most relevant part:
'Okay, Next one! On a scale of 1-10, how ticklish are your feet? My feet are a frickin' eleven, a twelve, a thirteen on a bad day! When I go get pedicures I'm the person who's like, gripping the sides of my chair, like, trying not to scream as they're scrubbing the bottom of my feet, my feet are so ticklish! My whole body is really ticklish.'
So uh, yeah, she seems like she'd be pretty fun to have locked in a pair of stocks, huh?
