An American visiting England walked into a hotel lobby.

“The lift will be down presently,” the receptionist told him.
“The lift?” said the American. “Oh, you mean the elevator?”
“No, I mean the lift,” replied the Englishman.
“I think I should know what it is called,” said the American. “Elevators were invented in the States.”
“Perhaps,” retorted the Englishman. “But we invented the language.”
