Fancy Dress Party

A bloke went to his mate's fancy dress party with nothing but a young woman on his back. "So what the hell are you supposed to be?" the host asked.

"I'm a snail." The bloke replied.

"What a load of crap!" the host spat. "How can you be a snail when all you've got is that young woman on your back?"

"You've got it wrong, mate," the bloke replied. "That's Michelle".
