Lucy from Peanuts perfectly shows why you should never beep a dog on the nose ... One of the things I've always loved about Peanuts comics is that Schulz was never afraid to allow Snoopy to behave out of character for comic effect. Usually, Snoopy is a little too forgiving of the characters, and he's put up with more than one or two beeps on the nose from Peppermint Patty. But when Crabby Lucy does it, in an attempt to humiliate him, he reacts with anger. Meanwhile, Lucy does not look too afraid, or annoyed, laughing as she runs away. Her malevolent streak remains intact, and perhaps this is why the reader is quick to forgive Snoopy for breaking character.
