A little girl asked her Mum, "Mum, may I take the dog for a walk around the block?"<br /><br />Mum replies, "No, because she is in heat."<br /><br />"What's that mean?" asked the child.<br /><br />"Go ask your father. I think he's in the garage."<br /><br />The little girl goes to the garage and says, "Dad, may I take Belle for a walk around the block? I asked Mum, but she said the dog was in heat, and to see you."<br /><br />Dad said, "Bring Belle over here." He took a rag, soaked it with gasoline, scrubbed the dog's backside with it and said, "Okay, you can go now, but keep Belle on the leash and only go around the block once."<br /><br />The little girl left, and returned a few minutes later with no dog on the leash.<br /><br />Surprised, Dad asked, "Where's Belle?"<br /><br />The little girl said, "She ran out of gas about halfway down the street, so another dog is pushing her home."
