Three Wishes - S3.E22

Endora gives Darrin three wishes. First he wishes that Larry goes to Hawaii instead of him. Then Darrin has to meet Buffy, a model, for a business lunch and Endora thinks the worst. It really gets serious when Darrin and Buffy fly out to Boston and a snowstorm grounds all planes from flying out. So Darrin gives Buffy his hotel room and he stays at the airport. At home, a message comes for Darrin and Samantha calls his hotel room in Boston only to hear Buffy at the other end. When Darrin comes home, Samantha thinks that he had an affair with Buffy and threatens to leave him, thinking that he used his wishes on Buffy. Darrin straightens her out by saying that he still have two wishes left. On his second wish, he wishes that Endora will appear before him and Samantha apologizes to Darrin for not believing him.
