Big Bang Theory Quote
Leonard: Go!
(Raj takes a deep breath and holds it)
Howard: Come on, Raj.
Leonard: You can do this.
Sheldon: There's no way.
Penny: What is happening?
Leonard: This is an Euler's disc. It's a physics toy that demonstrates angular momentum, potential energy and kinetic energy.
Penny: Aw, look at you watching sports.
Howard: We're betting to see if Koothrappali can hold his breath longer than the disc can spin.
Sheldon: Its weight and smoothness along with the slight concavity of the mirror mean it can spin for a long time.
Leonard: But Raj is from India which means he's no slouch at holding his breath.
Penny: OK, I want in. Ten bucks says I'll lose interest before that thing stops spinning.
Amy: (Amy enters) Hey, Sheldon, I found a great restaurant for date night.
Sheldon: Oh, eh, kinda busy right now.
Amy: Oh, an Euler's disc; fun.
Howard: Yeah, we're seeing if Raj can hold his breath longer than it.
Amy: Oh, immature.
