When a new child visited our Sunday school, the teacher greeted him and asked his age. The little boy held up four fingers.
"Oh, you're four," said the teacher. "And when will you be 5?"
The child stared at her and after a few seconds replied, "When I hold up the other finger."
One Saturday evening a man walked into a bar and said, "Excuse me, I would like a pint of beer." The bartender served the man his drink and said, "That will be four dollars." The customer pulled out a twenty-dollar bill and handed it to the bartender.
"Sorry, sir," the bartender said, "but I can't accept that."
So the man pulls out a ten-dollar bill, and the bartender rejects his money again. "What's going on here?" the puzzled man asked the barkeep.
Pointing to a neon sign behind the bar, the bartender explained, "This is a Singles Bar."
