One paragraph plot: Darrin is hosting a dinner for the clients and employees of the company. During the dinner, Mr. Barker, a client of Darrin, hits on Samantha. Samantha turns him into a dog before Darrin finds out about. When Darrin finds out about it, he was angry on Samantha for doing something like that on his client. Samantha becomes angry when Darrin doesn't believe her. So, Sam kicks him out of the bathroom. During the night, Mr. Barker (who turned into a dog) was attacked by a cat and run out of the house. Sam tries to get him back but runs into policemen. Policemen promised her to get the dog back to her and sends her back home. The next morning, Sam learns the dog's been found. So, she gets the dog and brings back to Darrin's company. Then Mr. Barker hits on Sam again. But this time, Darrin finds out about it and believes what Sam said last night. And everything's back to normal again.
Episode 3 is a funny episode because Sam turned Mr. Barker into a dog. At the same time, I was really angry at Darrin for not believing in Sam. Sam is his wife. He has to believe everything she says. But Darrin didn't. If I were Sam, I might still angry at him.
Anyway, this episode doesn't have that much contents. But some scenes are funny. I even laughed out loud. So, yeah, it's a good episode.
