Remember Nellie Oleson's dad in the '70s TV show, Little House on the Pairie, the series based on Laura Ingalls Wilder's books about life in the 19th century American Western frontier? Anyone? Man, I am dating myself here, but I do. Well, the actor who played long-suffering, kindly shopkeeper Nels, Richard Bull, just died at the age of 89. We're sad to see him go, but that's a good, long life! He died of natural causes at the Motion Picture & Television Fund's hospital after being admitted for pneumonia. Apparently he was just as loveable in real life as his TV character was, and actors are sending heart-felt condolences.
