Classic sitcoms from the ’60s rarely missed a chance to celebrate the holidays; shows like Gilligan’s Island, Bewitched, Mister Ed and The Beverly Hillbillies all found a way to work Christmas into their storylines. That is why it still surprises longtime TV fans that I Dream of Jeannie, a series that ran for five seasons and produced 139 episodes between 1965 and 1970, never featured a Christmas episode at all, despite offering up a Thanksgiving-themed episode in the second season.
