Costume Ideas.

Anyone have any good ideas for a Halloween costume? Id like to go for funny almost innappropriate historical figures but anything clever will work also. I was jesus last year, howard hughes the year before.

Ideas I have heard so far:
-Dress up as one of my friends
-Avian bird flu (if a good idea of how this is possible arises it could be funny)
-Zach Braff from Garden State wearing a trashbag in the rain. w/a girl wearing an epilepsy helmet
-Bin Laden or more likely an obscure terrorist
-A.C. Slater
-Ghandi or the Pope
-Global Warming (see avian bird flu)
-Captain Planet and or planeteers
