Jerry, George, Elaine, and Kramer head back to Manhattan after leaving a Mets game early, but have an altercation with a driver in a maroon Volkswagen Golf. George boasts about the comment ("That's gotta hurt!") he made during a new movie about the Hindenburg disaster titled Blimp. As they approach Fifth Avenue, traffic is blocked by the annual Puerto Rican Day Parade. They head towards a one-way side street, but are blocked by the maroon Golf, whose driver refuses to let them cross over. Elaine gets out of the car and gets a taxi. George leaves the car to see the movie Blimp in a nearby theater and repeat his funny comment for a new audience. When George makes the comment, nobody laughs. George blames a man with a laser pointer for upstaging him, and derisively calls him a prop comic. The man retaliates by shining the laser on him. Jerry makes an apologetic wave to the maroon Golf driver, who lets him by. As they pass, Jerry taunts the driver, only to find himself blocked by the taxi Elaine is in. George returns to the car, but the laser pointer is still shining on him. George can't see the man holding the laser and worries he will go blind if it touches his eye. Elaine tries to get past traffic by walking underneath the viewing stands, leading a group of similarly distressed people trying to find their way out to a dead end. They scream for help to the people above, but there is no access to the street from their location. Kramer becomes desperate for a restroom and spots an apartment for sale. To access its restroom, he poses as H.E. Pennypacker, a wealthy industrialist interested in the property. While there he sees the Mets game on the television. He tells Jerry, who visits the apartment to watch, posing as Kel Varnsen. George thinks he spots the laser guy and launches a sneak attack, grabbing and breaking what he thinks is the laser pointer only to discover it is a pen. Back outside, Kramer accidentally sets the Puerto Rican flag on fire with a sparkler, prompting Bob and Cedric and a mob of people to attack him. He runs back into the apartment. George also enters the apartment, as Art Vandelay, to wash the ink from his hands. Jerry realizes that with all three of them in the apartment, nobody is watching the car. They look out the window to find it surrounded by the mob. George tells Jerry that the Mets lost. When the parade is finally over, Jerry finds his car stuck in a stairwell. Elaine arrives, her clothes and hair filthy. They start walking home. George still has the laser dot on his lower backside.
