About this "The Simpsons" episode:

The Simpsons - Itchy & Scratchy & Marge is the 9th  episode of season 2 and number 22.
Maggie attacks Homer with a mallet, and Marge immediately blames The Itchy & Scratchy Show for turning her violent. Marge forms S.N.U.H. (Springfieldians for Nonviolence, Understanding, and Helping) and campaigns against the show. Eventually she successfully gets the writers to change their ways and make the show less violent. Meanwhile, Michelangelo's David goes on a coast-to-coast tour of the U.S., and the members of S.N.U.H. mobilize to protest it. Marge, however, states that she likes the statue and realizes that it is wrong to censor one form of art but not another and decides to give up her anti-cartoon violence protest.
