"Well, doc, I live in a trailer camp," the man explained, "And from where I am I can see this lovely chick next door. She's blonde and built like a brick shithouse.
She's so horny that every night I see her take a hot dog from the refrigerator and stick it in a hole in the floor of her trailer. Then she gets down and masturbates herself on the hot dog."
"And?" prompted the doctor.
"Well, I felt this was a lot of wasted pussy, so one day I got under the trailer and when she put the hot dog in the hole, I removed it and substituted my dick."
"It was a great idea and everything was going well. Then someone knocked at the door, she jumped off my hot dog and tried to kick it under the stove."
