Can’t quite say goodbye to Bea Arthur? Thanks to Hallmark Channel, you don’t have to. The station is imbuing its regular “The Golden Girls” programming with a “Best of the Dorothy Zbornak Episodes” tribute today and tomorrow, as well as a Sunday marathon, for a total of 19 hours of Bea. That’s in addition to an already scheduled “GG” marathon on Memorial Day. Set your DVR, pussycats!
