An infinite number of mathematicians walk into a bar. The first orders a beer, the second orders half a beer, the third orders a quarter of a beer, and so on...
After the seventh order, the bartender stops and says, “You fellas ought to know your limits!”
Two fellows 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 one.
"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?"
"That's right," he called back, "two pints!"
