Darrin has an important client, Rex Barker (Jack Warden) and he and Samantha give a dinner party for Rex and some others in the hope that Rex will sign an important contract with Darrin's firm. The meal goes extremely well but afterwards, Barker makes several very definite passes at Samantha who, in her fury, turns him into a small, scraggly dog. Instead of being understanding, Darrin is extremely angry because of the importance of the Barker account to the firm. Samantha is none too pleased about this and locks the dog outside while banishing Darrin to the couch.
Naturally, Endora can't help getting in on the act and sets a rather vicious cat on Barker which results in quite a few injuries for the dog! When Samantha finally returns Barker to himan form, we find that he hasn't learned his lesson because he once again, he tries his 'charm' on Samantha. This time, it's too much for Darrin and he punches him. Following this, he quits his job at McMahon and Tate but returns to work after Barker apologies for his behaviour and insists that Darrin continues to work on his account.
