Malcolm: Enjoy it?! Doesn't anyone besides me get it? The whole neighborhood hates us. So much that they throw a giant celebration just because we're gone.
Lois: Malcolm, that's not news. I'm just surprised they're so organized.
Malcolm: It doesn't bother you that everyone despises us?
Lois: No. These people need somebody to be mad at. Having us to hate gives the whole neighborhood something to bond over.
Hal: Your mother's right, son. Communities seek out a common enemy. If it wasn't us, they'd all team up against someone else. Probably a minority.
Lois: Malcolm, you can't spend your whole life worrying about what people think about you. They'll like you, they'll hate you, they'll think whatever they want to think, and then you die.
Malcolm: Is that supposed to cheer me up?
Lois: I don't know why you need cheering up. You are a teenage boy with a block party right outside his door. Now, you can stay in here and sulk if you want to, but your father and I are gonna go have a good time.
Hal: Come on, honey. Oh, my God, it's a lawnmower parade.
