Mark and Paul stopped into an English pub for a drink. They called the proprietor over and asked him to settle an argument.
“Are there two pints in a quart or four?” asked Paul.
“There be two pints in a quart,” confirmed the proprietor.
They moved back along the bar and soon the barmaid asked for their order.
“Two pints please, miss, and the bartender offered to buy them for us.”
The barmaid doubted that her boss would be so generous, so one of the fellows called out to the proprietor at the other end of the bar, “You did say two pints, didn’t you?”
