In this particular episode, Rhonda is put on the tickle chair by Howard (I think it's a different chair, though), and she's tickled on her feet and sides. She doesn't laugh when they tickle her feet, though, saying that she's normally ticklish there, but that day she has cold feet -- or something like that. But then, they get her sides, and they get her going.
