krusty the clown

Krusty the Clown is one of the many characters of the American animated comedy sitcom The Simpsons.
He is the long-time clown host of Bart and Lisa Simpson's favorite TV show, a variety show consisting of various kid-friendly sketches and often highly violent cartoons, most notably The Itchy & Scratchy Show. Despite his cheery onscreen persona, Krusty is actually a cynical, burnt-out, addiction-riddled smoker who is made miserable by show business but continues on anyway. He has become one of the most frequently occurring characters outside the main Simpson family and has been the focus of many episodes, some of which also feature Sideshow Bob.
