The Opera (Seinfeld)

The characters' lives begin to imitate the opera when Elaine's increasingly unstable boyfriend "Crazy" Joe Davola thinks she is cheating on him and stalks her and Jerry while dressed in a clown costume.

Elaine's boyfriend, "Crazy" Joe Davola, leaves Jerry a threatening phone message.

Elaine drops in on Joe's apartment where she discovers that he has a wall of pictures of her that he secretly took with his telephoto lens.

As Jerry and Elaine wait for them to return, they are asked by a street performer impersonating Canio for tips.

They are joined by Susan and Harry Fong, the man to whom George sold his ticket.
