|~ Oscar's catchphrase|
Oscar the Grouch is a green grouch troll and a major character/the main antagonist of Sesame Street franchise.
He always lives up to the species he is, a grouch, who is miserable, argumentative, unhygienic, rude, and just plain grouchy. He is the main antagonist from 1969 to 1990, one of the supporting characters from 1991 to 2005 and one of the main protagonists from 2006 to present. Like Big Bird, he was potrayed by the late Caroll Spinney and is currently performed by Eric Jacobson.
Oscar lives in a trash can between Big Bird's nest and 123 Sesame Street building. Oscar has had many pets, but his closest companion is a worm Slimey. He also has a girlfriend, a grouch named Grundgetta although a romantic relationship between two grouches is understandably rocky. Grundgetta usually calls him Oskie while he occasionally calls her Grungie. Telly and Elmo both consider Oscar to be a close friend, although Oscar disputes this since Telly and Elmo are the two monsters that Oscar doesn't like at all. However, Oscar reluctantly confirmed in Grouchland that Elmo was indeed his friend.
