I will always watch Get Smart, regardless how bad the movie was. And tho I liked Jeannie, I was a bigger fan of Bewitched. To be honest though, I'd watch Gilligan over both of them. Bob Denver (I believe played Gilligan) was hilarious. Random note, I've caught a few episodes of the old Twilight Zone with the Professor (Name?) in them. Pretty cool to see. I also watched one in which a young Dennis Hopper played a Socialist serving Hilters cause. I've got several more to watch on the DVR but I they're pretty good for being so old.
Speaking of old shows I recently watched, randomly they aired an episode of "The Commish" (I think on lifetime or bravo) and fell back into my childhood. My mom used to love watching that show.
