The presenter Alison Young, who's been in a few clips posted on here, mentioned that using a pummy stone to scrape hard skin off your feet tickles, to a phone caller on the show. So presumably she has been tickled herself by one, so it's sort of an admission! She was scraping a model's feet at the time to with this spatula type thing, but unfortunatley there was no tickling but some good shots of her feet. There's been beauty programmes on all day so i bet there's been a few other tickle mentions, as there often is on these type of programes.
