A Fancy Dress Party
A naked man was walking down the street with a woman on his back
Another man on the other side of the road asked, “Where are you going?”
The naked man replied, “To a fancy dress party.”
“What as?” asked the bemused gentleman.
“A tortoise”, said the naked man.
“Well, who is the woman on your back?” said the intrigued gentleman.
“Oh, that’s Michelle.”
