quite possibly my current favorite joke. highly disturbing. alexandra told it to me in math class.
A little boy was walking down the sidewalk, dragging a flattened frog on a string behind him. He came up to the doorstep of a whore house and knocked on the door. When the Madam answered it, she saw the little boy and asked what he wanted, because, y'know, he looked about twelve. He stared at her and said, "I want to have sex with one of the women inside. I have the money to buy it, and I'm not leaving until I get it." The Madam figured, hell, why not, so she told him to come in. Once he had stepped inside, she asked him if he had any specific girl in mind. He asked, "Do any of the girls have any diseases?" Of course, the Madam being the Madam said, "No! of course not!" He said, "well, I heard all the men talking about having to get shots after making love with Amber. THAT'S the girl I want." Since the little boy was so adamant and had the money to pay for it, the Madam told him to go to the first room on the right. He headed down the hall dragging the squashed frog behind him. Ten minutes later he came back, still dragging the frog, paid the Madam, and headed for the door. The Madam was rather curious, so she stopped him and asked, "Why did you want the only girl in the place with a disease, instead of one of the others?" He said, "Well, if you must know, tonight when I get home, my parents are going out to a restaurant to eat, leaving me at home with a baby-sitter. After they leave, my baby-sitter will have rape me because she just happens to be very fond of cute little boys. She'll get the disease that I just caught, and then when Mom and Dad get back, Dad will take the baby-sitter home. On the way, he'll jump the baby-sitter, and he'll catch the disease. Then when Dad gets home from the droping the baby-sitter off, he and Mom will go to bed and have sex, and Mom will catch it. In the morning when Dad goes to work, the milkman will stop by, have a quickie with Mom and catch the disease, and HE'S the son-of-a-bitch who ran over my FROG!"
