Question: Question: When did the person who voices Itchy begin acting professionally? Passage:The Itchy & Scratchy Show (often shortened as Itchy & Scratchy) is a fictional animated television series featured in the American animated television series The Simpsons. It appears as a part of The Krusty the Clown Show. Itself an animated cartoon, The Itchy & Scratchy Show depicts a blue mouse, Itchy (voiced by Dan Castellaneta), who repeatedly kills a black cat, Scratchy (voiced by Harry Shearer). The cartoon first appeared in The Tracey Ullman Show short "The Bart Simpson Show", which aired November 20, 1988. The cartoon's first appearance in The Simpsons was in the 1990 episode "There's No Disgrace Like Home". Typically presented as 15- to 60-second-long cartoons, the show is filled with gratuitous violence that almost invariably prompts uproarious laughter from Bart and Lisa. The Simpsons also occasionally features characters who are involved with the production of The Itchy & Scratchy Show, including Roger Meyers Jr. (voiced by Alex Rocco, and, later, Hank Azaria), who runs the studio and produces the show.
