I think new people who saunter over to this board should be checked out, otherwise we're in danger of having serious folk joining who aren't loony in any way.
I suggest we have a series of questions for those that wish to come on board.
1) Have you ever been to the Moon?
If the person you ask says "Yes", ask if he, or she, is Buzz Aldrin. If the reply once again is yes, and it's a 17 year old girl, you know she's lying, because she wouldn't have been born when Buzz went in a moonward direction. Tra-la-la-la-lee!
More questions need to be devised...
