Irv was a security guard at Sacred Heart Hospital until he was fired.
Irv was a jolly security guard, but had been gaining weight. When a rude man parked in an illegal zone, Irv was nice to him, but the man called him fat. Irv later tried to smother that man with a pillow and Carla and Turk had to restrain him. He was fired, and Janitor took his job for one day. ("My Choosiest Choice of All")
