Pig-Pen is a fictional character in the comic strip Peanuts by Charles M. Schulz. While amiable, he is a young boy who is, except on rare occasions, extremely dirty and attracts a permanent cloud of dust. History "Pig-Pen" is a nickname. In a 2000 Gallup Poll, Pig-Pen was found to be the fifth most popular Peanuts character. In strips up through 1980, Schulz spelled the character's name "Pig-Pen", with a hyphen; since 1981, the name has been spelled "Pigpen". He is also mocked by other characters because of his dirtiness. Pig-Pen is known for his perpetually filthy overalls and the cloud of dirt and dust that follows him wherever he goes. When he takes a deep breath (to sing, for example), the dust rises briefly around him. He sometimes refers to the cloud that surrounds him with pride as "the dust of ancient civilizations". He cannot seem to rid himself of the dust for more than the very briefest of periods — indeed, in spite of his best efforts, it appears that he cannot stay clean. He is referred to in an early strip as the only person who can get dirty while walking in a snowstorm. Nevertheless, on rare occasions he has briefly appeared clean, and hence unrecognizable. Once this was in order to impress Violet, of whom he was a bit fond. On another occasion (September 6, 1954), he managed to keep one side of his body clean and presented this clean side to Patty, causing her to believe that he was completely clean. In The Peanuts Movie (2015), Patty seems to have a crush on Pig-Pen and he seems to return these feelings. Once, after bathing and dressing in clean clothes, Pig-Pen stepped outside his house and instantaneously became dirty and disheveled, whereupon he declared to Charlie Brown, "You know what I am? I'm a dust magnet!" On another occasion, Pig-Pen decided it was important to have clean hands, but after failing to wash them, realized that he had "reached a point of no return." One notable exception is an earlier strip where he gets caught in a brief but heavy rainfall, and while trying to seek shelter, the storm ends, revealing him to be clean. He responds with disdain, stating that "in one minute the rain has washed away what took me all day to accomplish". Though Pig-Pen is proud of his uncleanliness, Charlie Brown is
