"The Fire" Season 5, Episode 19

George panics at his girlfriend's house when a small fire breaks out; he pushes women and children out of his way to get to the door. Elaine's annoying deranged coworker attends one of Jerry's shows and heckles him. In retaliation, Jerry visits her at work and heckles her. She in turn runs from the building and gets her pinky toe cut off.
