Stevie: Malcolm's...
Hal: Dammit, Stevie, I don't wanna hear it! You just behave yourself. You are a guest in this house!

Abe: He was a guest in your house! People should never yell at children! Especially children that aren't their own!
Hal: I apologized two minutes later! And Stevie accepted the apology! You know, he's not that fragile. So why don't you just relax!
Malcolm: Really.
Stevie: What?
