Wait right there... While wham bars may well have been the most awesome creation ever
in theory. I rarely bought them for one very good reason...
It was IMPOSSIBLE to fully remove the wrapper.
You'd pull it off and at least 1/4 of the wrapper would stick to the bar, so you'd typically have to eat some of the wrapper in order to get your wham fix.
Edit: Refresher bars often suffered from this predicament too.
