 One of Frasier s colleagues, Dr. Lawrence Crandell, is in town on a book tour to promote his latest on human sexual attraction and marital fidelity. He is in town without his wife, Valerie, he says a good way to test his theories. He says he has been celibate for 10 months while on tour. Rebecca construes a private conversation between the doctor and her as an unwanted come-on. In public, she is visibly hostile toward him; Sam and Frasier don t believe her story of the come-on as she believes. Sam and Frasier convince her that she could be wrong, so she apologizes to Dr. Crandell. The come-on this time however is unmistakable as is the hole is his sock as he runs his foot up her leg. Later in his hotel room, Dr. Crandell propositions the gullible young chambermaid named Maria just as Rebecca, with Sam clandestinely in tow, come by to have the doctor admit that he did come on to her. The doctor does do so, but Sam is too preoccupied with a certain chambermaid to hear. When a violinist meant to serenade the doctor and Maria comes by the hotel room, the doctor can t deny his actions. However, what s worse, Valerie surprises the doctor at the hotel. Sam, Rebecca, Maria and the violinist are forced into hiding in the closet since Valerie, by the doctor s own admission, is the scariest bitch on the face of the Earth. They are discovered in the closet and Rebecca wants to clear the air with Valerie. She not only fails to do so, but comes across as a raving lunatic. It s time for the closet foursome to leave while the doctor and his wife continue on their respective lecherous/bitchy lives.
