I was getting my basement done a few years ago, and I had a plumber come in to do some work. I cleaned out the entire basement except for 6 cans of Coke from 1993 when the Blue Jays won the world series (it was one of those collectable cans) that was sitting on top of the beam support in the basement. (I just forgot about it).
I wasn't at home to offer the guy something to drink, and my wife was occupied with our newborn and forgot to offer him a drink.
I came home after he left, but in a box of plumbing garbage that he left behind were 3 (THREE!!!!) empty cans that he had!
I mean, first off, they were piss warm, and they were 16 years old!!!!!!!!
I bet he was on the crapper that night! To this day my wife, who never drinks pop, tells me that if Coke can stay good for that long in a can, just imagine what crap is in it! To which I reply, I don't care, cause it tastes good with pizza or salt and vinegar chips!
