One of my favorite movies from the early 1980's was Bad Boys, starring a young Sean Penn in a stark departure from his previous role as the stoner surfer dude Jeff Spicoli in Fast Times At Ridgement High.
Bad Boys is largely set within the confines of a facility for hardcore juvenile delinquents. As good as Penn's performance was in the movie, the most memorable character in the movie is the intelligent but twisted Jewish misfit named Horowitz, who shares a cell with Penn's character.
Below is a funny scene from the movie wherein Horowitz retaliates when the alpha male bully of the inmates, the towering Viking Lofgren (played by Clancy Brown) taunts him with anti-semitic language. As crazy as Horowitz is, you just gotta love his ballsy, take no-shit response to someone who physically outmatches him.
