Some Australian Humor  (must be done w/an Australian accent)

 A bloke went to his mate's fancy dress costume party with nothing but
 a naked girl on his back.

 "So what are you supposed to be?" the host asked indignantly.

 "I'm a snail," the bloke replied.

 The exasperated host asked, "How can you be a snail when all you've got is
that naked girl on your back?"

The bloke replied. "That's Michelle."
