My Dad once told me that in the town of Andover, Hampshire, where I grew up there was a big controversy over a group of townsfolk who used to have wife swapping parties, where house keys were thrown into a pot and whichever key the women picked went home with that guy. A young lady who was the assistant at Noyce's Butcher Shop (would you like me to wrap up your meat Sir?) was also heavily involved with all the "fun" and that caused further embarrassment when the story came out.
