Bewitched - Season 2 - Eps 34: Man's Best Friend
Well, it's been almost a month that Samantha has used no witchcraft and she and Darrin celebrate. What can possibly break up the moment? A warlock named Rodney who still has a flame burning for Samantha. She tells him flat out that she likes Darrin, and what does he do? Turns himself into a shaggy dog. Rodney is hell-bent on breaking up the Stephens marriage (Hey, maybe he and Endora should get together!) that even Darrin can't even take much more of it. He finds out that Rodney is indeed the dog and really lets him have it. Then Rodney gets it again when his mother comes and fetches him.
