After a girl's night out prank backfires, Lois finds out that Peter frequently donated sperm before they got married, and convinces him to let his potential children seek him out if they want to. Much to their surprise, Peter's unknown children number in the hundreds, including a young man named Larry who's a dead ringer for Peter himself in his 20s.
Tropes:
- Half-Human Hybrid: Turns out Peters masturbation habits in the bathroom has created a race of not just half-human/half-alligators and half-human/half-rat hybrids in the sewers beneath Quahog, but also human-alligator-rat hybrids.Alligator/Rat Peter: We have fun down here.
- Money Dumb: The reason why Peter became a sperm donor in the first place is that he needed the extra money because he spent the money that was supposed to be for his wedding on a course that taught him how to make dial-up noises with his mouth.
- Mythology Gag: Larry shares the same name as one of Seth's early characters who's a prototype for Peter.
- Older Hero vs. Younger Villain: Though not an outright villain, Larry does serve as the episode’s antagonist, and ends up fighting Peter in the climax.
- Sassy Black Woman: One of Peter's children is a black woman.
- Strong Family Resemblance: Peter's genes show in all his kids, regardless of gender, race, age, or nationality.
