1. Major Anthony Nelson - I Dream Of Jeannie (1965-1970)
Major Anthony Nelson is an astronaut who discovers a genie in a bottle after one of his missions. The genie, known as Jeannie, falls in love with him. Unfortunately her playful hijinks create endless trouble for Major Nelson as he tries to keep her powers a secret from everyone but his best friend and fellow astronaut Major Roger Healey. Nelson makes several space flights during the show, with Jeannie often showing up in the ship and wreaking havoc. Boy, this show brings back memories for me. Not only was Jeannie one of my first prepubescent crushes (along with Mary Ann from Gilligan's Island and Marcia Brady), but the show itself is a part of my childhood. I grew up watching syndicated reruns of I Dream of Jeannie, Batman, The Lone Ranger, Superman, The Brady Bunch, and Gilligan's Island, one right after the other, each weekday after school.
That's my list. Are there any I missed? Let me know in the comments.
