Little Suzie asked her Mom, "Mom, may I take the dog for a walk around the block?" Mom says, "No, because the dog is in heat." "What's that mean?" asked the child. Mom says, "Go ask your Father. I think he's in the garage." Little Suzie goes to the garage and says, "Dad, can I take Trixie for a walk around the block? I asked Mom but she said the dog was in heat and that I should ask you." He took a rag, soaked it with gasoline, and scrubbed the dog's butt with it and said, "OK, you can go now but keep Trixie on the leash and only go one time around the block." Little Suzie left and returned a few minutes later with no dog on the leash. Dad said, "Where's Trixie?" Little Suzie said, "Trixie ran out of gas about halfway down the block and there's another dog pushing her home."
