Cavewoman Shad (Imogene Coca) is disgusted by the filthy cave of stranded astronauts Mac (Frank Aletter) and Hector (Jack Mullaney) and vows to get them each a wife. Surveying the available homely women leaves their stomaches churning. Mac feels it's their best course of action though to be trusted among the prehistoric cave people until they can repair their space capsule. But, only for Hector to be married. Much to their surprise, Shad brings her lovely, voluptuous daughter Mlor (Mary Grace). Hector becomes frustrated by the pre-marital customs, which includes building a stone wall to live in a room in the same cave as her parents. He unintentionally proposes by hitting Mlor on the head. As he's venting to Mac, the plump Blob (Mary Foran) enters the astronaut's cave to rest and Mac accidentally hits her on the head. Boss (Cliff Norton) sees this act of proposal for his daughter and welcomes his "son", along with Clon (Mike Mazurki). The astronauts pack and run off into the jungle. They keep running into Clon, however, and choose a return over threatening dinosaurs and crocodiles. Held as prisoners, Mac escapes, but is running out of time to save Hector from being boiled in a bubbling pit. I didn't find this as an especially funny episode and the payoff of the plot seemed weak.
