Like most of the Kroffts's productions, the show's opening sequence provides the setup of its fanciful premise: While loading food into various compartments to prepare a rocket for an upcoming mission, Barney instructs Junior to hit the "lunch" button, but Junior mistakenly hits the "launch" button. The rocket blasts off and takes them on various misadventures on alien planets. Typically, in each episode, their spaceship (a
NASA lunar module) would be captured by aliens (one being played by
John Carradine, who so impressed Denver with his acting skills during a scene that he was left speechless and missed his cue, requiring another take) and taken to some strange planet, or the spaceship would merely land somewhere. Then, either Barney and Junior, or the ship, would be taken away by the strange creatures on the planet. After some weird mission was carried out, the two astronauts would be reunited with the spaceship and be off on their next mission. ==Cast==
