S03E17: Sam in the Moon

Darrin is mesmerized by the moon footage on TV and shows Samantha, but she is not interested because she has been there before. Endora wants Samantha to go shopping with her- in Tokyo! They go to a little place where they get warlock tea. Darrin finds the tea and thinks that Samantha really did go to the moon. He has it analyzed and the druggist brings his cousin from Nassau County (Darrin thinks it is NASA) to give him the results: It is really tea, not moon dust.
