Oscar

Oscar the Grouch is a furry, green Grouch who lives in a trash can on Sesame Street. In fact, he loves trash so much that he's rarely seen outside of his trash can. His trademark song, explaining his passion for refuse, is "I Love Trash." Like all Grouches, Oscar's mission in life is to be as miserable and grouchy as possible, and pass that feeling on to everyone else. When a visitor knocks on his trash can invariably interrupting him from a nap or an important task Oscar greets them with a snarl. He complains that he wants to be left alone, when he's left entirely to himself, he's dissatisfied there isn't anybody around to irritate or complain to. (Sesame Street series 3 of 6)
