Resealable chocolate wrappers? What the flipping flip?
Reminds me of the days when you used to get beer in seven-pint cans ("party sevens" or "bumpers"). We used to get them at Christmas, and one year, my mum suggested that we should get one of those tap things to put on the can: "so you could make it last instead of having to drink it all at once". She got quite confused (and then angry) at the instant, simultaneous reaction from me and my dad, of uncontrollable hysterical laughter.
