Big Bang Theory Quote
Mary Cooper: Let me straighten your tie.
Sheldon: No, no, no, it's all right. It's supposed to be a little asymmetrical. Apparently, a small flaw somehow improves it.
Mary Cooper: I can see that. Sometime's it's the... imperfect stuff that makes things perfect.
Sheldon: (a thought strikes him) Excuse me.
(he hurries out of the room)
Mary Cooper: Case in point.
