There was a little boy named Johnny who used to hang out at the local corner market. The owner didn't know what Johnny's problem was, but the other boys would constantly tease him. They would always say he was dumb. To prove it, sometimes they would offer Johnny his choice between a nickel and a dime, Johnny would always take the nickel -- they said, because it was bigger. 

One day, after Johnny grabbed the nickel, the store owner took him aside and said, "Johnny, those boys are making fun of you. They think you don't know that the dime is worth more than the nickel. Are you grabbing the nickel because it's bigger, or what?" Johnny turned toward the store owner and a big grin appeared on his face. 


Johnny said, "Well, if I took the dime, they'd stop doing it. So far I've saved $20!
