Transcript:
Charlie Brown and Schroeder are sitting on the curb. The former points up in the sky and says, "See? That's the sun..."
He continues, "Now, if you'll just wait a bit..."
It gets darker and they are still sitting and waiting.
It is night and Schroeder smiles as Charlie Brown points up in the sky and says, "There! See? That's the moon!"
Original comic:
That’s pretty random for Peanuts.
