Big Bang Theory Quote
Leonard: What are you grinding about?
Sheldon: Penny's brain teaser this morning. She and Koothrappali emerge from your bedroom. She is disheveled and Raj is dressed only in a sheet. The sole clue: "It's not what it looks like".
Leonard: Just let it go, Sheldon.
Sheldon: If I could, I would. But I can't, so I shan't.
