My mother used to work in a doctor's office with a British woman, a WWII "war bride". She always had one handy. It was the first that I had seen a Round Tuitt. That was in the 1970s. The "Jinx Remover Spray" is getting a little old at this point too. It's been a common gift shop item for a long time.
I've often thought that there might be some off-label use for "Anti Monkey Butt Powder" (a legitimate product).
