Barney (Chuck McCann) and Junior (Bob Denver), two NASA employees, were loading supplies on a spaceship when Junior mistakenly hit the launch button (Barney had said "lunch, not launch"). The spaceship sent them to a distant planet where they encountered Honk, a furry creature with a horn on the top of his head they called Honk (Patty Maloney). They spent most of the season trying to avoid the various creatures/aliens they encountered while they tried to get home. In the final episode, Barney and Junior gained access to time machine-like device that took them back to the spaceship, right before Junior hit launch. Missing their friend Honk, Barney and Junior repeat the launch and start their adventures all over again. Only 16 episodes were made. Although very campy, it was a fun show. Several big-name actors, Like John Carradine, played monsters.
