Plays Andy Sipowicz on NYPD Blue. He is the most kickass cop on TV. Though this is New York, Dennis Franz came from the mean streets of Chicago. You'll see him beat somebody's ass on every episode, and occasionaly say something funny that you wouldn't expect to hear. However, he's gentle when it comes to women.
After Andy kicked that one drug-dealers ass, he took him down to the station. He questioned another guy and finally said "Don't mess with me or I'll piss on your shoe."
