(As Bart is sleeping, Homer bursts in with a butcher knife and a tray)
Homer: (shouting and holding up the knife) BART, DO WANT SOME BROWNIES BEFORE YOU GO TO BED?!
(Bart screams)
Homer: Come on, let me cut you a brownie while they're still hot.
Bart: (sighs in relief) Dad, I'm kind of edgy right now. I'd appreciate you not running in my room screaming and brandishing a butcher knife.
Homer: Why? (brief pause) Oh, right, the Sideshow Bob thing. I'm sorry, boy. (kisses Bart and leaves)
(Suddenly, the door bursts open again, and Homer comes in wearing a hockey mask and holding a chainsaw)
Homer: BART, DO YOU WANNA SEE MY NEW CHAINSAW AND HOCKEY MASK?!
(Bart screams)
Homer: (turns off the chainsaw) Oh, sorry. What am I thinking?
