Bart: I don't believe it! Principal Skinner. Well, well, well, I
never thought I'd win _this_ easy.
Skinner: Hmph. This has nothing to do with you, Simpson. I have many,
many issues with my beloved smother -- mother.
Homer: Bart, leave that man alone with his pain and sit down.
Bart: [abashed] OK.
[Homer laughs at Skinner, makes crazy noises at him]
