At First

I could not for the life of me figure out why this one was listed under ethnic jokes;

There was a man who wanted a pure wife. So he started to attend church to find a woman. He met a gal who seemed nice so he took her home. When they got there, he whips out his manhood and asks "What's this?" She replies "A cock." He thinks to himself that she is not pure enough. A couple of weeks later he meets another gal and soon takes her home. Again, he pulls out his manhood and asks the question. She replies "A cock". He is angry because she seemed more pure than the first but, oh well. A couple of weeks later he meets a gal who seems real pure. She won't go home with him for a long time but eventually he gets her to his house. He whips it out and asks, "What is this?" She giggles and says "A pee-pee." He thinks to himself that he has finally found his woman. They get married but after several months every time she sees his member she giggles and says, "That's your pee-pee." He finally breaks down and says "Look this is not a pee-pee, it is a cock." She laughs and says "No it's not, a cock is ten inches long and black."

Now I know, jealous much?
