Mr. Blonde's real name in the movie Reservoir Dogs. The part was played by Michael Madsen who's quite an accomplished, but not too well known actor. Vic Vega was the guy that cut the cop's ear off while dancing to the song "Stuck in the Middle" by Stealers Wheel. This ear scene is what made that song infamous in the cult following of this movie. Anyway Vic Vega was the psycho amongst the other crew hired for the jewelry heist in Tarantino's first movie.
