Big Bang Theory Quote
(Sheldon takes a drink of water)
Raj: Sheldon, that's my water.
Sheldon: Oh dear Lord!
(he runs into the bathroom)
Leonard: That's not your water.
Raj: I know.
(Leonard smiles)
Sheldon: (off-screen) Where's the mouth wash?
Raj: (pulling it out from underneath the cushion next to him) Where indeed?
