Since Halloween is my favorite holiday and it always bothers me when people make poor costume choices, I decided to come up with some ideas for the MMA universe.
Matt Hamill - a fighter
Dana White - wear a wig and be "Dana White circa 1988"
Anderson Silva - a giant hot dog
Joe Rogan - shave his beard, put on a suit, and be Ari Gold
Michael Bisping - Peter Venkman from Ghostbusters
Rich Franklin - Lloyd Christmas
Frankie Edgar - a Gotti boy
Houston Alexander - Beldar Conehead
Kenny Florian - Don Flamenco from "Mike Tyson's Punch-Out"
Brandon Vera - a giant sleeping pill
