Leonard Hofstadter
- [first lines]
- Leonard Hofstadter: Go!
- [Raj takes a deep breath and holds it]
- Howard Wolowitz: Come on, Raj.
- Leonard Hofstadter: You can do this.
- Sheldon Cooper: There's no way.
- Penny Hofstadter: What is happening?
- Leonard Hofstadter: This is an Euler's disc. It's a physics toy that demonstrates angular momentum, potential energy and kinetic energy.
- Penny Hofstadter: Aw, look at you watching sports.
- Howard Wolowitz: We're betting to see if Koothrappali can hold his breath longer than the disc can spin.
- Sheldon Cooper: Its weight and smoothness along with the slight concavity of the mirror mean it can spin for a long time.
- Leonard Hofstadter: But Raj is from India which means he's no slouch at holding his breath.
- Penny Hofstadter: OK, I want in. Ten bucks says I'll lose interest before that thing stops spinning.
- Amy Farrah Fowler: [Amy enters] Hey, Sheldon, I found a great restaurant for date night.
- Sheldon Cooper: Oh, eh, kinda busy right now.
- Amy Farrah Fowler: Oh, an Euler's disc; fun.
- Howard Wolowitz: Yeah, we're seeing if Raj can hold his breath longer than it.
- Amy Farrah Fowler: Oh, immature.
- [last lines]
- [Sheldon has been haranguing the cafeteria]
- Leonard Hofstadter: What brought that on?
- Sheldon Cooper: Well, last night Amy was angry with me because I've been foolishly telling people about certain personal matters.
- Howard Wolowitz: That's understandable.
- Sheldon Cooper: Mmh, I know that now. At first, I thought she was cranky because of her horrific menstrual cramps, but... it turns out no, she was genuinely mortified.
- Raj Koothrappali: [walks in with a Gucci bag] Hello-o!
- Penny Hofstadter: Oh, someone's been shopping at Gucci.
- Raj Koothrappali: Yeah, I saw something for Halley, and I couldn't resist.
- Bernadette Rostenkowski: That's so sweet of you.
- Raj Koothrappali: Yeah, it's a crushed velvet baby cape.
- Howard Wolowitz: Oh, no. Now we have two.
- Penny Hofstadter: That must have been expensive.
- Raj Koothrappali: Yeah, it was, but it's my father's money and I'm mad at him.
- Leonard Hofstadter: What's going on with your dad?
- Penny Hofstadter: And if you really want to hurt him, I look great in Chanel.
