"The Old Man" - Season 4 Episode 18 of Seinfeld First Airs
"The Old Man" is the fifty-eighth episode of the American television sitcom Seinfeld.
It was the 18th episode of the 4th season. It aired on February 18, 1993.
Jerry, Elaine and George volunteer to help the elderly. Jerry gets assigned to a bad-tempered old man with a foreign housekeeper that he claims is trying to steal his possessions. Elaine is repulsed by the goiter problems of the woman she is visiting and George depresses his assigned senior citizen by questioning his outlook on dying.
Kramer and Newman try the business of selling some of Jerry's old records to a used record store but are not satisfied with the results. The man Jerry is responsible for tells him that he wants to get rid of some of his "junk", including a large amount of old records which Kramer and Newman show up later to pick up. The man bites Kramer's arm, causing him to jerk back and launch his dentures in to the garbage disposal. Jerry loses track of his man when they try to take him to the dentist to repair his dentures which were promptly destroyed after the garbage disposal was turned on, mistaken for a light switch.
Meanwhile, Elaine discovers that her old woman had an affair with Gandhi, and one of the stories she tells directly mirrors what George had said to the housekeeper about him "dipping my head in oil and rubbing it all over your body".
The search for Jerry's old man leads to everyone (including the old man's son) bursting in on George having oil rubbed on his head by the housekeeper.
The episode ends with the two old men, in the diner, discussing their relationships with women, much like the conversation Jerry and George have at the beginning of the episode.
