Ah, my home country doing weird stuff again. /== Never gets old. *sighs* Realistically, I think it would be useful if you were camping (it'd be harder for a bread to get into a can of bread than a bag, I suppose), but I can just see people getting it for dumb reasons. (Plus, cans make everything taste metallic. I mean...ew. :thumbsdown
Yeah, diet water's a really dumb concept. Some of those are as bad for you as a whole candy bar and such. It's brought me to the conclusion that anything that's not just plain water that I'm drinking is probably bad for me. XD
