Fangface (1978)

Season 1: Episode 8

A strange space creature frozen in ice crashes into a US space station, and astronauts are sent out to retrieve it. It is held in the freezing room, but a button on the creature's belt activates, and the ice begins to thaw. On Earth, the gang is given a tour of the new space shuttle, and Sherman plays out the old ""lunch, not launch"" joke by pressing the red button in hopes of filling his stomach. Direct view of the moon changes him into Fangface, and the gang can only wait until the shuttle autopilot takes them to the space station. Back on the space station, the alien creature is loose, and he is stealing the crew's minds. Only Fangface can track him down and stop him.
