Go to the scene where Potiphar's wife is sedeucing Joseph. Go to where Potiphar walks in and gets mad at Joseph. At the very end, Potiphar is handed one of those old-time phones, where you have to hold the one part to your ear to hear what the person on the other line is saying and you have to talk into the mouthpiece connected to the phone. Well, he holds the phone so that the mouthpiece is turned facing his wife and then talks into it, completely missing the mouthpiece. The person on the other line couldn't possibly hear him!
