Junior hangs out at the local grocery store. The neighborhood boys think Junior is two bricks short of a load and like to tease him.
To prove it, the boys offer Junior his choice between a nickel and a dime. He always takes the nickel, they say, because it’s bigger.
One day after Junior grabbed the nickel, the store manager got him off to one side and said, “Junior, those boys are making fun of you. They think you don’t know the dime is worth more than the nickel. Are you grabbing the nickel because it’s bigger?”
Junior says, “No. I grab the nickel because if I took the dime, they’d quit doing it!”
