I always make costumes out of things I have lying around.

This year's costumes have been:

water polo player. speedo, ball, cap, stunning physique.
surfer. wetsuit, board, zinc oxide (actual stuff lifeguards/spicolis use. doesn't end up looking like semen a la above spicoli costume).
arab shiek. classic costume, given that i'm brown and know how to fly, yet not land, planes.

I gotta come up with something fresh for tonight and tuesday.
