The Simpsons Nudity List

Last updated June 6, 2004

We chafe when people call The Simpsons "just a cartoon," but sometimes this attitude works in our favor. This list shows how this can be. It covers not just moments of nudity on The Simpsons, but also times when a character appears in his or her underwear, or when nudity is used as the basis of a joke. Do you think a live-action show, even one on Fox, can get away with all this? Fortunately, The Simpsons can; after all, it's "just a cartoon." -- Benjamin Robinson

Please note: This is a list of instances of, or references to, nudity on The Simpsons or its related merchandise. We regret that we cannot serve, e-mail, or otherwise make available pictures of OFF naked, nor list links where such material might be available. Also, we are not accepting such material at this time.
