April Fools Ideas for forum

[Tannerman]

I wonder if anyone has come up with modifications or ideas for their forums for April Fools Day. One idea that would probably be simple (though I don't have the code) is simply flipping the whole forum upside down on the screen.

Anyone try something like this (or other crazy ideas?).

im probably not desiging this hack but maybe when a member logs in it says their account has been suspended and they have to signup again so when they are redirected it says "April Fools!"
