This reminds me of a story, and I'm not sure if it's an urban legend. Maybe someone will remember. I think it was a tv show and one of the questions to a new wed husband was "Name an unusual place you had sex". He says the car or something. The wife comes back and says, "my arse"?

You should go and listen to Fidlar - Bad Habits...

books, anything heavy, your aunt's dead body... only joking.
