Stretcher-bearer: [speaking to the nurse] We're going to do a test. I'm going to use this object. If it doesn't change colour and stays white, then it automatically means you are competent and reliable, and can stay in our group. If it changes colour, there are two possibilities. First, it might turn blue. If it turns blue, then it automatically means that you are competent, but unreliable. Therefore? There's no therefore. It doesn't really matter if it turns blue. It's just something I said. The second and worst possible outcome is for this club to turn red. Which means automatically that you are too unreliable to and too incompetent to stay with us. Let's see.

Stretcher-bearer: It changed. It turned red. I'm afraid you'll have to go.
