IN THE CAR - now that sounds like fun. I tickled someone in a GMC Yukon XL, one time. I used to be a car salesman, and I was training a new girl. I was showing her the interior features of the Yukon XL (because that was what I was supposed to do). At one point, I showed her how to take the head rest off of the front passenger seat. She asked, "Is that so somebody can do this?", and put her foot up on the top of the seat, right in my face. "Yeah," I said, "and so someone can do this." and before she could react, I thrust the headrest back into the slots, and pinned her foot underneath it. Then, with no protesting from her, I took off her shoe and tickled her foot for about 30 seconds, before letting her go. I had to let her go, because she was starting to laugh real loud, and I didn't want to draw too much attention. Anyway, there's my favorite in-car tickling experience. 😎
