Oscar the Grouch is a Muppet character on the television program Sesame Street. He has a green body (during the 1969–1970 season he was orange), has no nose, and lives in a garbage can. His favorite thing in life is trash; evidence for this is the song "I Love Trash". An early version of the green Oscar debuted on The Flip Wilson Show in 1970 and Oscar's explanation for that was that he had vacationed at Swamp Mushy Muddy, where the dampness had turned him green overnight. In a 2003 appearance, Oscar stated that while his time in Swamp Mushy Muddy made him appear green, he is still in fact orange underneath all the slime and mold. (He's just never taken a bath).

While appearing to be the size of a normal trash can, Oscar's residence is presumably larger inside than the exterior would suggest, as evidenced by the fact that Oscar has noted through the years that it boasts such amenities as a swimming pool, bowling alley and a piano.

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, although when he's left entirely to himself, he's dissatisfied -- there isn't anybody around to irritate or complain to.

Here is a clip of Oscar, with his pet worm, Slimey:
