The Simpsons1989

Homer:
That guy has gotta go!

Marge:
Hmm, I know how you feel. But he is good with the kids.

[pan upward to Lisa's room, where Otto is telling her a bedtime story by candlelight]

Otto:
So the lady drove faster, but the strange car kept banging into her from behind...

[Lisa gasps]

Otto:
So she swerved off the road into the woods, and lost the other car. And then, she realized that 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 Simpson:
Did the maniac kill her?

Otto:
Natch! And you know how I know?

Lisa Simpson:
How?

Otto:
Because... *I* was that maniac.

[Lisa's scream shakes the whole house]

Otto:
[hastily] I was just kidding!
