My Favorite Martian
Man or Amoeba
S1 E5:
Mrs. Brown's daughter Angela (Ann Marshall, in her final series appearance) is assigned to write a school paper on the theories of Professor Newton Jennings (John Fiedler), who believes that Mars is inhabited only by primitive amoebae and inverterbrates. Hoping to get the facts straight, Martin (Ray Walston) helps Angela finish her paper--and as a result, the girl gets a failing grade! Infuriated, Martin decides to expose Jennings as a fraud, but the results are not quite what anyone expects.
