A Jewish chap was in a supermarket in Baltimore. He saw an African American woman trying to get her young child to put down a candy bar he had picked off the shelf.
"Latrell, you put that down! It's not kosher!"
Intrigued, the young man decided to investigate. "Excuse me, ma'am, are you Jewish?"
"So why did you say that?"
"Why? I'll tell you why. Cuz I see all those Jewish mothers saying that to their kids -- and it works, so I decided to try it."
