The episode begins with Mr. Krabs talking about his money until he shrieks due to seeing Old Man Jenkins coming to the Krusty Krab. He tells SpongeBob how Old Man Jenkins acts in his restaurant and how he annoys his customers a lot.
He tries to kick him out, but that makes the customers mad at him for disrespecting the elderly. SpongeBob tells him he should ask him politely, leading to Mr. Krabs making him do the talking. When he talks with Old Man Jenkins, he realizes how poor of a life he has and tells everything he said to his boss.
Mr. Krabs starts trying several methods to kick Old Man Jenkins out. He first turns up the heat, but Jenkins ends up feeling cold in this environment. He then tries to put on loud music, but Jenkins sleeps through this.
He gets his father to kick Old Man Jenkins out as he's older than him. Jenkins shows him his grandfather, leading to them bringing out many of their ancestors until all of them are in the Krusty Krab. The ancestors kick Mr. Krabs and Old Man Jenkins as they are bumming them out and want to party. The two stay at the Chum Bucket for the time being, much to Plankton's dismay.
- Old Man Jenkins saying, "Respect your elders!"
- Mr. Krabs getting extremely angry whenever Old Man Jenkins causes havoc at his restaurant.
