When I was a kid - must've been like 8 or 9 (don't really want to think I was much older, given my actions to follow) - I was at the mall with my mom and we went into Spencer's. They had a doll with suction cups on the hands that you put on a car window and the rear end facing the public/traffic. Then there was a squeeze pump that would cause the doll to pull down its pants and moon the outside world.
I saw this and when my mom and I walked out of Spencer's and into the larger mall I said something along the lines of "Mom, look at this!" and proceeded to moon the entire mall. I did not get my pants back up. She grabbed my arm, pulled me up in the air, and proceeded to spank my bare ass. I don't know if my bum or face (from embarrassment) were redder.
I wonder if Spencer's still sells those?
