Bart: Otto!
Otto: That's what my driver's license says!
Otto: So the lady drove faster, but the strange car kept banging into her from behind. So, finally, she swerves off the road into the woods and lost the other car. And that's when she realized the man in the other car wasn't trying to hurt her. No, he was trying to warn her... about the ax-wielding maniac hiding in her back seat!
Lisa: Did the maniac kill her?
Otto: Natch! And you know how I know?
Lisa: How?
Otto: Because... I was that maniac!
Lisa: [screams]
Bart: Whoa! Otto-man, you work here?
Otto: Oh yeah. During the day all my friends are in school so I got a job as a certified bloodletting tech-dude!
Homer: Now let's get this show on the road.
Otto: Okay. Let me wash up. [humming Black Sabbath's “Iron Man”]
Bart: Any new tattoos, Otto?
Otto: Oh, funny you should ask, man. This morning I woke up with this one.
Bart: Cool. I want one.
Otto: Huh. Not 'til you're 14, my little friend.
