She was briefly tickled on her feet as was her sister but its very quick. It was on Eight Simple Rules after John Ritter passed away. I can't remember the episode or even what it was about, but it was shortly after his passing. It was at the end of the show and the whole family was on the bed, I think in the mother's room and C.J. (David Spade) feeling left out asks if he can join them. He dives across the bed at their feet and the girls immediately start laughing and saying something like, "Cut it out" and the scene fades out. Of course it is all acting, so who knows...
