I cannot tell a lie. I stole this from another thread.

A little girl asked her Mom, 'May I take the dog for a walk?' Mom replied, 'No, because she is in heat.' 'What's that mean?' asked the child. 'Go ask your father. I think he's in the garage.'

The little girl went to the garage and asked, 'Dad, may I take Belle for a walk? Mom said the dog was in heat, and to talk to you.'

Dad said, 'Bring Belle over here.' He took a rag, soaked it with gasoline, and scrubbed the dog's backside with it to disguise the scent. He said 'OK, you can go, but keep Belle on the leash and only go one time round the block.'

The little girl left and returned a few minutes later with no dog on the leash. Surprised, Dad asked, 'Where's Belle?' The little girl said, 'She ran out of gas about halfway down the block, so another dog is pushing her home.'
