I like the story of the American woman in Fortnum & Mason's. She spies the Christmas Crackers.
One of the liveried attendants in morning suit approached:
"May I help you, Muddum?"
"Yes, what are these, Sir?"
"They are Christmas Crackers, Muddum...."
"What in Hell's name are those?"
"They are put on One's (Evian - reading this?), Christmas table, Muddum, a wrapping with a small pull in them that pops when you have two people tugging from either end. When it comes apart, inside there is a small present, a paper hat and a joke or amusing saying."
"How much are these, then?"
"£500 for a box of six, Muddum"
"Goddd, in whose name buys these then?"
"The Queen has a few boxes at her Christmas table, Muddum."
"I'll take 8 boxes then, Sir."
"Thank you, Muddum."
