My old boss has a Halloween party most years. (It's his (and his wife's) favorite holiday, so they go all-out.) I went as a doping cyclist. (Borrowed a US Postal jersey and a coordinating cap, bought one of those syringes used to dose children's liquid medicine and taped it to my arm with medical tape. I wore jeans with it, though--it was chilly and my former boss was the departmental dirty old man.) Not doing anything this year.
