Fawlty Towers S02E02 - The Psychiatrist

A psychiatrist and his wife — also a doctor — come to the hotel for a weekend break, and cannot help but notice the eccentricities of their host, who is perturbed when he discovers their professions. A very attractive Australian girl (Luan Peters) also visits. She goes on to have certain awkward interactions with Fawlty as he seeks to catch Mr Johnson (Nicky Henson) with a non-paying guest that Johnson has in his bedroom.
