Little Johnny came home from school one day slightly confused. His mother was Jewish and his father was black. So Johnny says, "Mom, am I more Jewish or more black?"
"What does it really matter? You'll just have to ask your father", his mother tells him. So Johnny's father gets home from work and Johnny asks the same question, "Dad, am I more Jewish or more black?" "What kind of a question is that, does it really matter? Why do you want to know if you're more Jewish or black?" asks his dad.
"Well, it's like this dad. Tommy down the street wants to sell his bicycle for $50, I don't know whether to Jew him down to $25, or wait till its dark and steal the fucker.
