"The Trip" is a two-part story (the forty-first and forty-second episodes to air) of NBC's popular sitcom, Seinfeld.
Airing on August 12, 1992 and August 19, 1992, it kicked off the fourth season of the show.
Kramer is arrested when he is mistaken for "The Smog Strangler," a serial killer roaming the streets of Los Angeles. While also in L.A., Jerry and George try to help resolve the accusation. They use a pay phone to call the police and they say they have some important information regarding the stranglings. Two policemen in a police cruiser come to pick them up and take them back to the station. On their way, the officers see a man (Clint Howard) trying to break into a car. They arrest him and put him in the back with Jerry and George. They have to stop again when they get a police call regarding to the "Smog Strangler" and happen to be close to the scene. Jerry and George want to make sure Kramer is not imprisoned, so they open the door of the car, and, in their hurry, leave the door open. The man who was breaking into the car escapes.
Kramer is taken to the police station and is interrogated by the lieutenant. He has a nervous breakdown in the interrogation room and is reduced to hysterical sobbing, making it seem like he did the stranglings. While he is being questioned, the lieutenant receives a phone call stating that the Smog Strangler has killed another victim, and so Kramer is allowed to leave. After Kramer is exonerated, Jerry and George decide to return to New York, but Kramer opts to remain in Los Angeles. However, by the end of the episode, Kramer has returned to New York and is once again living across the hall from Jerry. He offers no explanation for his return.
It turns out that the Smog Strangler is actually the man that was in the back seat with George and Jerry, the one they accidentally let escape. It is broadcast on a news program that his whereabouts are unknown.
