A guy goes to a Fancy Dress party carrying a good looking girl on his back and both are dressed in plain casual clothes.
After a while the host fronts up to the pair and says: “OK – I give up what are you two?”
The guy replies: “I’m a turtle!”
The host is nonplussed. “What?? How are you a turtle… and what’s she?
The turtle replies: ” Oh, that’s just Michelle.” 😀
