    • Leonard: Do you really need the Honorary Justice League of America Membership card? Sheldon: It's been in every wallet I owned since I was five. Leonard: Why? Sheldon: It says, "keep this on your person at all times." It's right here under Batman's signature.

    • Sheldon: I'll have a diet Coke. Penny: Can you please order a cocktail? I need to practice mixing drinks. Sheldon: Fine... I'll have a virgin Cuba Libre. Penny: That's... rum and Coke without the rum. Sheldon: Yes, and would you make it diet?

    • Raj: (drunk) Where did my life go, Penny? (everyone is shocked) Raj: One day, I'm a carefree bachelor, and the next, I'm married and driving a minivan to pee-wee cricket matches in suburban New Delhi. Penny: Are you talking to me? Raj: Is there another Penny here?

    • Penny: I need some guinea pigs. Sheldon: Okay, there's a lab animal supply company in Reseda you can try. But if your research is going to have human applications, may I suggest white mice? Their brain chemistry is far closer to ours. Penny: I swear to God, Sheldon, one day I'm going to get the hang of talking to you. Leonard: His mom's been saying that for years.

    • Sheldon: When I was a little boy and got sick, which was most of the time, my mother would read [The Monkey and the Princess] to me. It's about an Indian princess who befriends a monkey who was mocked by all the other monkeys because he was different. For some reason I related to it quite strongly. Penny: I know the reason. Leonard: We all know the reason.
