I know someone who actually BROKE the bed while she was having sex with some bloke she had picked up at the pub.
I know, because I was in the next room on the piss with her flatmates and we all heard the loud crack, thump, then bad language, and got to check out the broken bed afterwards.
Many years later, this person was a long-time receptionist at a medical centre in Gisborne and my GP (at the same medical centre) made the comment one day that nobody had any dirt on her (she was always taking the piss out of her workmates over various things), so I told the GP about the time she broke the bed while indulging in humpy-pumpy. A huge smile came across his face and he gave me the thumbs-up. Presumably he dragged it up at an appropriate moment during staff drinkies!
