What happens when you're traveling in space with your whole family and your ship flies off course? When you're saddled with evil saboteur Dr. Zachary Smith and his robot? Television magic!

Lost In Space followed the misadventures of the Robinson family and Dr. Smith, their incompetent and comic obstructionist who gets them into trouble every time. I followed the misadventures of the Smith family on television for the entire 3-year run of the series. First in black-and-white and later in color, the show gave us a first look at what it would be like to actually get lost in the vastness of space.

I liked young Will Robinson because he was smart and good at science, but my favorite character was the robot. A "Class M-3 Model B9, General Utility Non-Theorizing Environmental Control Robot", he could also sing and play guitar, and feel happy or sad. For a robot, he also had a great wit — particularly for sarcasm and mockery and especially when it came to Dr. Smith.

The robot only said his famous catchphrase "Danger, Will Robinson!" one time (season 3, episode 11: "The Deadliest of the Species"), but it was never forgotten. It's made its way into pop culture, casual conversation and was even used as the tagline for the 1998 movie, making the lovable robot truly immortal.
