Quote from Peter in Crazy Chin
Hank: You know, Robert, I've always wanted to ask you something. Robert: What is that, sir? Hank: Why do you touch your food to your chin before you put it in your mouth? Amy: Dad! Robert: No, it's okay, Amy. Pat: You know, I noticed that too. Why do you do that, Robert? Robert: It's- It's nothing. It's just a little habit of mine, that's all. Amy: Yeah, he hardly ever does it. Peter: Eh, that's all right. Every family has their oddball. With us, it's Mom.
