Plot Summary

For the Invention Exchange, Joel presents a safety device for motorcyclists. The Mads, anticipating the Mad Scientists' Convention, show off their device for getting rid of unwanted guests. For the day's experiment, Joel and the bots are forced to watch the first tedious chapter of "Radar Men from the Moon" (1952), with Commander Cody, as Joel explains to Tom Servo what a serial is. Their feature film is the cheesy Mexican horror flick, "The Robot vs the Aztec Mummy" (1958). Meanwhile, the threesome do their best to fend off an attack on the Satellite of Love by demon dogs, who are attracted to the spaceship's bone-like shape.
