Lisa: Excuse us, Rabbi Krustofsky?
Rabbi K: Oh, what can I do for you, my young friend?
Bart: We came to talk to you about your son.
Rabbi K: I have no son! [slams the door]
Bart: Oh great, we came all this way and it's the wrong guy.
Rabbi K: [opens the door] I didn't mean that literally! [slams the
door]
