Sheldon: How can you sleep? I'm not done making you feel better. I still have to put a cold rag on your head, sing to you and apply VapoRub to your chest.
Amy: You, you want to rub something on my chest?
Sheldon: Yes. All over it.
Amy: Maybe we should start with that.
Sheldon: Now you're being a responsible patient. Now, you may notice some tingling.
Amy: Oh, I'm counting on it.
