"Flat frog" joke
There was this little boy about 12 years old walking down the sidewalk pulling a wagon and dragging a flattened frog on a string behind it, when he comes up to the doorstep of a house of ill repute.
He knocked on the door, and the madam came to answer it, saw him and asked what he wanted.
He said he wanted what she was selling inside, had the money to buy it, and wasn't leaving until he got it. She thought she would have some fun with him, so she told him to come in.
Once he got in, she told him to pick one of the girls he liked; he asked her if any of the girls had any diseases, and of course the madam said no. But he said he'd heard that all the men were talking about having to go to the hospital and get shots after making love with Mabel, and THAT was the girl he wanted, and that he had the money to pay for it.
The madam told him to go upstairs and go to the first room on the right. So he headed down the hall dragging the frog behind him.
Ten minutes later he came back down still dragging the frog. He paid the madam, and picked up his wagon and headed out the door, at which time the madam stopped him and asked him just why he picked the only girl she had 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. When they leave, I'm going to screw the baby-sitter, who happens to be very fond of cute little boys, and give her the disease that I just caught.
When mom and dad get back, dad will take the baby-sitter home, and on the way, he'll jump her bones, and he'll catch it. When dad gets home, he and mom will go to bed, they'll make love, and mom will catch it. In the morning when dad goes to work, the milkman will deliver the milk, and he'll have a quickie with mom, and he'll catch it, and HE'S the son-of-a-bitch that ran over my FROG...
