IMDB article for Dale McRaven, creator of Perfect Strangers:

In 1989, there was a scintillating dustup about the Dale McRaven-created program Perfect Strangers. McRaven had been committed to killing off the characters (the cast is safe) in a two-part episode called Father Knows Best, but two young fans of the show (aged 5 and 11) started a campaign to save them. McRaven ultimately relented and years later publicly thanked them for saving his show.

It's not in the Wiki articles for either McRaven or the show. The show was in the 30s in the Nielsens at the time.
