I saw this the other night live and found the video wikifeet.com/videos?page=2 at around the 3:14 mark. She says when she normally gets pedicures the foot scrubbing tickles her.
She formerly did the local weekend news in Philadelphia. There was a segment with the Pet of the Week; one show a dog was licking either her feet of her legs and she said it tickled. This occurred while a adoption information was being shown on screen so it was not visible.
