People still do those?
I did that when I was like ten.
Anyways, I SORT OF cheated because instead of eating the whole chocolate piece I ate like a half, and saved the other half for the "real" day.
Sometimes, though, the chocolates would fall out of their little spots and be everywhere behind the slots... so it was just a whole mess.
I LOVE those chocolates though - and I don't know where to find an actual chocolate bar that tastes like that.. *Drools*
