The boy walked into the back room and said: "There is some asshole out there who wants to buy only a half a head of lettuce."
As he was finishing saying this he turned around to find the man standing right behind him, so he added: "...and this gentleman wants to buy the other half."
The manager okayed the deal and man went his way.
Later the manager called on the boy and said: "You almost got yourself in a lot of trouble earlier, but I must say I was impressed with the way you got yourself out of it. You think on your feet and we like that around here. Where are you from, Son?"
The boy replied: "Canada, sir."
"Oh really? Why did you leave Canada?", asked the manager.
The boy replied: "They're all just whores or hockey players up there."
"My wife is from Canada!"
The boy replied: "Really? What team did she play for?"
