Arthur, Season 1 (1996)

The rest of the episode takes place about year earlier. Arthur has no glasses and his friends are in Mr. Marco's class

Mr. Marco:
This quiz is to be completed in class. No talking! [writes math problems on the blackboard.]

Arthur:
That's a seven, right?

Francine Frensky:
No, it's a two!

Arthur:
That's a one?

Francine:
No, it's a seven.

Arthur:
That's a seven.

Francine:
No Arthur, it's a nine, stop bothering me!

Mr. Marco:
(clears throat) Ahem! Mmm! (handing out test results) These are your test results. Anybody with four or more mistakes should see me after class for extra homework.

Francine:
[has all questions right, but Arthur has them all wrong] I guess math's not your best subject.

Arthur:
I have a headache!

Buster Baxter:
Yeah, sometimes Francine gives me a headache too.

Francine:
(Offended, putting her head up with her eyes closed) Hmph!
