Played by: Barbara Eden and Larry Hagman

She's a supernatural being in a legendary midriff-baring and cleavage-enhancing costume. She's undoubtedly the sexiest sitcom girl of the '60s—so sexy that 20 years later Andrew Dice Clay was still affected enough to crack dirty jokes about her.

And don't forget, he's an astronaut. According to Axe Body Spray, nothing beats an astronaut in terms of attracting the ladies. So this couple is on fire. Even if the onscreen interactions were a tad chaste.
