Quotes

Zack: I asked for the most expensive one they have. They said it was $200 and I said I want a more expensive one. And then, they said it was $300.

Marissa: We want to have a baby, but we can't do it on our own.
Zack: It could be because of the game me and my frat brothers used to play where we kicked each other in the balls over and over.

Notes and Trivia

Near the end of the episode, when Penny is telling Leonard that she supports his decision, the front of the refrigerator is clearly visible behind Penny. Attached to the freezer door are two pictures of Leonard and Penny. One is of them in her apartment on her couch. The other appears to be a still image from The Nerdvana Annihilation (2008). It shows Leonard, without his glasses, holding Penny in the elevator shaft. Other items on the refrigerator include a periodic table, the apartment's official flag, post-it notes, a notepad, and multiple take-out menus.

Title reference: Zack asks Leonard to be a sperm donor so that he and his wife can "propagate" (reproduce).
