A man went to his friend’s Halloween fancy dress party with nothing but a young woman on his back.
“So what the heck are you supposed to be?”, the host asked with a puzzled look on his face.
“I’m a snail”, the man replied.
“How can you be a snail when all you’ve got is that woman on your back?”,his friend asked.
“Nah, you’ve got it wrong, mate”, the man replied, “that’s Michelle”.
