Hey Arnold!, Season 4

Principal Wartz:
Young man, I hold here in my hand your permanent record. Now you still have a chance to save yourself. Just tell me who the real mooners are. Tell me their names and I won't have to enter this terrible black mark on your record.

Arnold:
I can't do that.

Principal Wartz:
[to Arnold] You understand that your permanent record will follow you all the way to Jr. High?

Arnold:
I understand.

Principal Wartz:
And you still won't tell?

Arnold:
No.

Principal Wartz:
Then you leave me no choice.

Harold:
I did it, it was me! I'm sorry, Arnold was completely innocent! I'm the mooner! I'm the mooner!

Stinky:
I'm guilty too!

Sid:
And me! We all did it together!

Stinky:
Arnold had nothing to do with it!

Sid:
He was just a pawn in a horrible twisted prank!

Harold:
He's a saint! He's a saint! [Arnold smiles]

Principal Wartz:
Well, young man, I suppose this lets you off the hook... for now. [closes the top of the permanent black marker]
