Little Jacob is always being teased

Little Jacob is always being teased by the other neighborhood boys for being stupid jew. Their favorite joke is to offer Jacob his choice between a nickel and a dime -- Little Jacob always takes the nickel. One day, after Jacob takes the nickel, a neighbor man takes him aside and says, "Jacob, those boys are making fun of you. Don't you know that a dime is worth more than a nickel, even though the nickel's bigger?" Jacob grins and says, "Well, if I took the dime, they'd stop doing it, and so far I've made $20!"
