Amy: I think I'm too sick to go to the funeral.
Sheldon: You're sick? You poor kid. Well, see ya.
Amy: Sheldon, aren't you gonna take care of me?
Sheldon: Me? No. No, I'm not that kind of doctor.
Amy: But our relationship agreement clearly states that when one of us is sick, the other must take care of them.
Sheldon: Oh, no, I see the confusion. No, the intent behind that clause was to force you to take care of me when I'm ill. When you're feeling better, you'll think that's funny.
