Arthur, Season 4 (1999)

Arthur sits in the classroom with Buster, Francine and Muffy. Binky walks into the room while keeping his back turned to Arthur

Francine:
Arthur, why didn't you just apologize?

Arthur:
[still pissed off] Oh, come on! She wrecked my plane! Why can't anybody see my side of this?

Muffy:
Uh, because you're wrong.

Francine:
[turns to Binky at the next table] Hey, Binky. Did you hear that Arthur hit his little sister?

Binky:
Well, I haven't seen Arthur. As far as I know, Arthur isn't even here.

Francine:
Binky is so upset about what Arthur did that he won't even look at him.

Class has started

Mr. Ratburn:
When the day and night are of equal length, it's called the equinox.

The bell rings and Binky immediately runs out

Molly:
You socked that kid yet?

Binky:
Haven't see him. [walks away] I am so smart.
