Homer: So, I realized that being with my family is more important than being cool.
Bart: (unimpressed) Dad, what you just said was powerfully uncool.
Homer: You know what the song says: "It's hip to be square".
Lisa: That song is so lame.
Homer: So lame that it's... cool?
Bart and Lisa: (dismissive) No.
Marge: Am I cool, kids?
Bart and Lisa: (dismissive) No.
Marge: Good. I'm glad. And that's what makes me cool, not caring, right?
Bart and Lisa: (dismissive) No.
Marge: (frustrated) Well, how the hell do you be cool? I feel like we've tried everything here.
Homer: Wait, Marge. Maybe if you're truly cool, you don't need to be told you're cool.
Bart: (puzzled, uncertain) Well, sure you do.
Lisa: (bewildered) How else would you know?
