A co-worker of mine and I spent most of our day trying to create MMA Halloween mash-up costume ideas. Thought the UG might want to jump in on the fun.
Examples of ones we came up with:
Pamela Anderson Silva
George Michael Bisping
G.I. Joe Rogan
Ben HenderSons of Anarchy
Bruce BufFergie
Danny Glover Texiera
Meg Ryan Bader
Frankie Edgar Allen Poe
T.J DillaShawshank Redemption
Duane 'Bang' Ludwig Van Beethoven
Bonus points if you Romo your entry, extra bonus if you actually dress up as one of them.
Oh just thought of another one: Josh Barnetflix
Sorry Another one: Citizen Cain Velasquez
Jack Black Dana... Last one
"The Ghetto Man" Joe Charles Bronson.
How about a UG mashup...
One Glove Jimmy Rustler 
Bu 
James Toney Danza
Ronda Rowdy Roddy
Rampage Jackson Teller
Was hoping was a picture montage. I am disappoint.
