Quote from Hal in Malcolm's Girlfriend
Lois: This is all your fault, Hal. You're the one who bought him that acne medicine. Hal: I thought we were safe. I mean, he's still goofy-looking. His head is, like, five times too big for his body. Lois: We shouldn't have to worry about this with Malcolm. He's gifted. He's in genius classes. Girls aren't supposed to be interested in him until he's 28 and a billionaire! Hal: Certain things are beyond the boy's control, Lois. It's his genetics. Girls, they just swoon. Sorry, what am I telling your for? You battle with it every day. There's nothing we can do.
