In college, couldn't think of a costume. Had a beard and mustache that I was going to shave off soon, so I shaved off the right side ofmy beard and the left side of my mustache.
Another year, used my sister's eye shadow to make realistic looking bruises. Added red food coloring and Karyo corn syrup for blood. Gauze and a torn and singed t-shirt and viola, I'm an accident victim. As the night wore on and I got hot the corn syrup started running down my face. Every so often I would touch my "wound" and lick my finger.
