Synopsis by Hal Erickson
Rabid Red Sox booster Carla Tortelli (Rhea Perlman) gets steamed when boorish Yankees fan Ed Kellner (Ron Karabatsos) drops in at Cheers. So inflammatory are Ed's abrasive anti-Boston insults that Carla ends up slugging the guy. As a result, Ed threatens to slap an enormous lawsuit on Sam (Ted Danson) unless Carla is immediately fired. But never fear, there's a "sweet revenge" finale in this classic episode.
