This is me a couple years ago:
I've gotten so fat I'm gonna wrap my self in aluminum foil and go as a baked potato.
You can further the brotherhood of man by eliminating class.
You can lift the wage earner up by equalizing earnings.
You can bring about prosperity by overturning the holders of power.
You can strengthen the weak by eating the the strong.
You can help the poor by destroying the rich.
This is from a few years ago.
I was thinking something like that would be hilarious, or anything like the jumpsuit or "pimp" outfits like were in the funny pics thread recently. I've also been considering going as William Wallace from Braveheart, just as an excuse to try out a kilt for a day. Last year I went as "Dr. Gonzo" /Oscar Zeta Acosta, friend of Hunter S. Thompson, and absolutely nobody got it.
