Principal Skinner has brought Bart’s parents in for a conference.
Skinner: But worst of all, he drags down the grades of anyone who sits near him. Just look at this pattern!
[Skinner holds up a diagram of Bart’s head surrounded by D’s and F’s, in turn surrounded by A’s and B’s.]
Homer (laughing): Hey, that looks like Bart!
Skinner: And turning to the 3-D map, we see an unmistakable cone of ignorance.

Marge (shamefully): Put it away! Put it away!

Homer: Ah, this thing will do anything. Watch. I'll ask it how many leagues in a furlong.

Lisa is punished by having to write “I will not do math in class” repeatedly on the chalkboard.
