Lenard: (stained his hand with ketchup) Oh, dammit. Can I borrow the napkin?
Sheldon: I’m sorry, no.
Lenard: But you have a whole bunch of ‘em.
Sheldon: Yes, I’ve moved to a four-napkin system. Lap, hand, face and personal emergency. If you like starting tomorrow I’ll have a guest napkin, but I’m afraid there’s nothing I can do for you for today.
Lenard: (still gets a napkin)
Sheldon: Good luck, that’s the face napkin.
