Sheldon (to Wolowitz): You'd hit particulate soil on a colloidal suspension.
Sheldon: (elaborates after seeing Howard's confusion) Mud.
Sheldon: DANGER! DANGER!
Wolowitz: It is I, Sir Howard of Wolowitz.
Sheldon: I'm surprised you struck out with Penny, apparently she's a big 'ol five.
Raj: What's with him? *Pointing at Sheldon sleeping*.
Leonard: Penny is keeping him up at night.
Howard: Me too! But probably in a different way.
Leslie: Hello men. Sheldon.
