Kramer's coffee table book about coffee tables is now in prepress at Pendant Publishing. Reviewing the proofs, Elaine's coworker Toby bounces off the walls with relentless enthusiasm that Elaine cannot keep up with. Jerry is anxious to impress a notable magazine critic attending his next show, and Kramer brings Toby, promising she is a "great laugher". Having never attended standup, Toby loudly cheers and boos nonstop, throwing Jerry off-guard. Toby is unapologetic for heckling to "express herself".
George is dating Robin, a comedy club waitress. He attends her young son's birthday party, and is disappointed that the birthday clown does not remember Bozo the Clown. Discovering a small kitchen grease fire, George starts a panic, then shoves the kids, Robin and her elderly mother, and the clown to the ground in a mad dash and escapes alone. The fire is easily put out, and everyone is appalled when George shamelessly defends himself as "leading" the charge to escape.
Jerry gets bad press for Toby's heckling flustering him on stage. At George's suggestion, he gets the "ultimate comedian's revenge" by heckling Toby at work in return. Toby runs out into the street in distress, where a street sweeper runs over her foot and cuts off her pinky toe. Later, Kramer recounts his race against time to deliver the severed toe on ice to the hospital, forcing him to fight off a gunman and drive a runaway bus while making stops all at the same time. George is astounded by Kramer going to such lengths for a toe.
When Toby returns to work with her toe reattached, Elaine gets sidelined entirely as Toby receives the office's outpouring of sympathy, and a promotion to senior editor that Elaine was in the running for. Toby's first order of business is putting Kramer's book on sale.
George, inspired by Kramer, vows to Robin at the comedy club that he will change. A prop comic's water gun robbery gag startles George, who starts another panic and shoves everyone aside. Fellow comedians hail Jerry for standing up to hecklers, but Jerry's hard-won second chance to impress the critic is ruined by the gun scare.
