Bobby and the Neighborhood Bullies
Every day Bobby was teased by neighborhood bullies. Their favorite joke was to offer Bobby a choice between one dime or one nickle.
Bobby always chose the nickle and the bullies would laugh hysterically, call Bobby a dummy, then ride off on their bicycles.
One day Betty witnessed the cruel teasing. She took Bobby aside and said, "Bobby those mean boys are making fun of you. Don't you know that even though the nickle is bigger than the dime, a dime is worth more than a nickle."
Bobby grinned and said, "Betty, If I took the dime they would stop offering the nickle. I've made $20 bucks in nickles so far this summer."
