This is something I've never thought of. Water can't go bad. Food can go bad, but Twinkies last forever. So, I go to the basement fridge two days ago, to be aghast that there's no Coke. I grab the only reserve Fridge Pack off the top of the thing, pop it in, don't think anything about it. Yesterday, I go down and grab a can. Take a sip. Note that the can's bottom is dented; no prob, it happens all the time. But I notice the date on the bottom says "APR05". ... can Coke go bad?
