Synopsis
Arthur and his friends are out playing basketball when suddenly Binky steals Buster's turn and shoots a basket. Muffy, Prunella and Francine all call him out for being rude and having no manners, but Binky replies that he gets what he wants without them and walks away whistling.

Francine says that they can't let Binky get away with that and Muffy suggests signing him up for a manners class. None of the group can really imagine Binky in a manners class, but Brain does think that Muffy might be on to something in that Binky needs to learn how to act more polite. Arthur suggests that they could all try acting rude around him so he can see how it feels. They all agree, Brain calling it an "interesting behavior study" and Muffy saying that it won't be easy for her to act rude, but she'll try.

Later that day, Arthur and Buster encounter Binky watching a street performer and stand in front of him, blocking his view. Binky complains that he can't see, but the two just tell him that he'll need to move. They then gush about the street
