Jack incurs the wrath of a Regal Beagle patron named Max (guest star Terry Kiser) who turns out to be a psychotically jealous type. Max will threaten anybody who ogles his lovely girlfriend April (guest star Pamela Brull). Things eventually get out of hand, with Max remaining a scary presence in Jacks' life, to the extent that he's afraid to go out in the street. It's up to Larry to come up with a plan that will hopefully motivate Max to go away.
While some of the material in this episode may be uncomfortable to watch now, knowing of John Ritters' fate, overall this is a simply hysterical story. All of the cast members bring their A game, and are very, very funny. Kiser, who will likely always be best known as the title character in the "Weekend at Bernie's" movies, is fun to watch, and has some great moments, such as his method of coming through a door. Richard Kline as Larry and Don Knotts as Mr. Furley are likewise a hoot. The antics at the "funeral" are positively gut busting, particularly where the fly and the flowers are involved.
There are some wonderful lines here, such as the one in this reviews' summary. It's first heard coming from Cindy's mouth (referring to the supposed stopping of Jacks' heart during the night), but is even funnier when Max says it. Mr. Furley's actions and reactions during the funeral sequence are just too much.
The coda is just right, with Jack proving that no matter what life throws at him, he'll always be an insatiable guy.
Nine out of 10.
