Bart: [watching Mongo's rampage] I don't know what it is.
[Van Johnson bursts into the office]

[realizes Bart is on the opposite side of the room, and turns around]
Van Johnson: Sheriff! Mongo's back! He's breaking up the whole town! You've got to help us, please!

Van Johnson: Oh, thank you, Sheriff! Oh, thank you very much! Thank you!
[runs to the door and flings it open]
Van Johnson: [shouting] The fool's going to... I mean, the sheriff's going to do it!
