Hi, I know it's Friday, but I think it's time to bring an end to swapping statistical "humour". If anyone really is interested I suggest you try the StatJokes list, you can find details at http://www.stat.ucla.edu/phplib/lists.phtml While I'm ranting I'll also take this opportunity to remind you that generally, if responding to a query posted to the list, you should send your reply to the original poster rather to Allstat. If appropriate, a summary of responses can be sent to the list by the original poster in due course. Allstat is intended to be an information provider, rather than a discussion list.
