(Penny snores)

Sheldon: You might want to speak in a lower register.

Leonard: What?

Sheldon: Evolution has made women sensitive to high pitched noises while they sleep, so that they’ll be roused by a crying baby. If you want to avoid waking her, speak in a lower register.

Leonard: That’s ridiculous. (Penny snores again.)

Sheldon: No, (lowering his voice dramatically,) that’s ridiculous.

Leonard (doing likewise): Fine. I accept your premise, now please let’s go.

Sheldon: I am not leaving until I’m done.

Leonard: O-o-o-oh! (Collapses against wall).

Sheldon: If you have time to lean, you have time to clean.

Leonard: Oh, what the hell.
