The show's pilot came under fire for depicting mercury additives in childhood vaccines as a credible cause for autism, an idea which had gained a great deal of media attention in the late 1990s but which was thoroughly disproved by the time the episode was produced. The American Academy of Pediatrics asked that a disclaimer to be placed in front of the show, reminding viewers that no mercury is present in routine vaccinations and that the mercury-autism link has been rejected by the medical community. The producers opted to show a disclaimer after the end credits stating that the "persons, companies, products or events" were fictional, referring viewers to the CDC's web site on autism for more information.
