Smart Kids illy's house is packed with relatives for Christmas dinner. Grandpa calls 8 year old Billy and starts asking about school, girlfriends and other stuff he can think of. After a while, grandpa notices that Billy is loosing interest in the conversation. In an attempt to keep Billy interested, he pulled out a $10 bill and a $20 bill. He shows both bills to Billy and tells him that he can keep any one he chooses. Billy reaches over and grabs the ten dollar bill. Grandpa is pretty surprised and upset about the unwise decision his grandchild made, pulls out another $10 bill to see if it was a mistake. Again, he tells Billy to take one of the bills and keep it. Billy grabs the other $10. Grandpa again is surprised and upset. He takes Billy over to one of the uncles and shows him how dumb Billy is in choosing the $10 over the $20. Grandpa goes on and on showing every uncle and cousin and each time Billy chooses the $10 over the $20. Grandpa finally shows the stunt to daddy. Daddy's quite surprised but doesn't pay too much attention at the moment. A few hours later, daddy, who is very concerned about Billy's poor decision, walks up to him and asks him if he knows the difference between a $10 bill and a $20 bill. "Of course," answers Billy. "So why did you always choose the $10 over the $20?" asks dad. Billy, with a wide smile answers, "Well dad, if I would have chosen the first $20 bill, do you think grandpa would have played the game fifteen more times?"
