re: What are you gonna be for Halloween?

I won't be able to do this since I already have a different costume, but i'll throw this out to anyone who doesn't know what they want to do yet:

grape costume

Plus sharpie to draw faces

Equals 'member berries (from South Park)

Bonus points if you cut out speach bubbles out of dry erase board, write "'member" on the top line, and let people write in their member berries at your party.
