You bought a joke remote control from the back of a magazine a few weeks back and it finally turns up. You don’t exactly expect it to work, but it seems kind of funny: it has two buttons on it. One says “freeze” and the other says “strip”. It doesn’t come with an instructional manual. Your sister’s snobby friend Claudia is staying over and as a joke you point the remote at her and press FREEZE. To your shock she stands totally still, frozen in place like a statue. You keep her there for a minute or two, hardly believing it has worked, before you press STRIP and her shirt disappears. Unfortunately it seems this has also removed the freezing effect because she is suddenly furious at you for somehow removing her shirt and starts to yell at you. You quick hit FREEZE again and decide to see how far you can push this…
