fifi

"Mom, may I take the dog for a walk around the block?" a little girl
asked.
"No, I don't think so. Fifi is in heat,"
replied the mother. "What does that mean?" asked the child. Embarrassed
and not wanting to get into a
biological discussion with her young daughter, the Mother said, "Oh, just
go ask your father. I think he is in the garage."
The little girl goes to the garage and says, "Dad, may I take Fifi for a
walk around the block? I asked Mom, but she said that Fifi was in heat,
and that I had to come talk to you." Not wanting to have the biological
discussion either, the father said, "Bring Fifi over here." He took a rag, soaked it
with gasoline, and scrubbed the dog's rear end with it. "Okay, now you can
go for a walk but keep Fifi on the leash and you can only go around the block once."
The little girl left, and returned a few minutes later with NO DOG on the
leash. "Where is Fifi?" her father asked.
"She should be here in a minute," advised the daughter. "She ran out of gas
about halfway down the block and another dog is pushing her home."
