If you give up an envelope which contains either 2A or A/2. Then its value is 5/4 of A. You get back either 2A or A/2, so the new envelope has a value, Surprise, of 5/4 A. Nothing paradoxical about that. Paradoxical is how can people be so blind and consider just one part of the story...it's a joke
