Basil Fawlty: [to Polly] Oh, I see, it’s my fault, is it? Oh, of course, there I was, thinking it was your fault because you had been left in charge, or Manuel’s fault for not waking you, and all the time it was MY fault. Oh, it’s so obvious now. I’ve seen the light! Well, I must be punished then, mustn’t I?
[spanking himself]
Basil Fawlty: You’re a naughty boy, Fawlty!
