Bart is standing in front of a Smokey the Bear statue, who has an electronic voice and a little quiz to administer. Bart and Smokey have the following exchange.
Smokey: (electronic intonation) Who is the only one who can stop forest fires?
Bart: (examines response panel, which has two buttons, marked "you" and "me", and presses "you")
Smokey: (electronic intonation) "You pressed YOU, meaning me. This is incorrect. You should have pressed ME, meaning you."
