Not me personally, but in 1980, while attending college, I lived in a house with seven bedrooms, all rented to students, with common kitchen and bathroom. There was no living room, it had been converted into one of the seven bedrooms.
Anyway, somebody caught 'Norm', one of the tenants, rubbing one out when they opened the bathroom door which he had failed to fully close. The next day, a sign was posted in the bathroom:
"This is a teepee for you to pee pee,
Not a wigwam, for you to beat your tomtom.
