punchline/ Liz Sorensen

One of my best friends has a younger brother that was planning to be in the elementary school talent show. He'd been practicing his cute little poem for weeks and his parents and grandparents were all going to be at the talent show to hear him recite his poem. The poem was something about a little boy who kept trading things like one dollar for two pennies because two is better than one. It was a poem a cute a little elementary school student would say.
His parents were in the audience with the video camera recording and his grandparents were right by their sides. The little boy walked up on to the stage, cleared his throat and recited "A mexican and a black person are riding in a car. Who's driving?"
The audience went silent and heads turned toward his parents. Then he went on to finish his joke "Neither of them are, the cop is!"
