Sorry guys. Everyone's starting to think along the right lines, but aren't quite there yet. Let me know if you need more clues or want me to explain why any answers so far are wrong and I'll put it in a spoiler.

This is a great one - I heard it many years ago and it took me a while to get it, but have always remembered it as one of my favorites! Glad to see it's got people puzzled here too!
