they don't sell cans in my country, and I'm happy about that......you can re-seal them, they lie everywhere on the street and nature in the countries that have them, and the bottom 1/4 of a can always tastes like crap!
Well, I use to pile cans on my desk too.. but had an accident where i accidentally drank a half empty can of coke that was a week old and was used as a spit can. After about 30mins of trying to hurl and feeling stupid, i decided to never let things piled up again.
computer desk:7 coke, 6 mountain dew
printer desk: 3sprites, 2 cokes, 4 cherry cokes
window sill next to chair: A HUGE WALL TOO LARGE TO COUNT! anyone else ever built a pop can wall against their window?
on floor: a few dirty coffee mugs, with evaporated/fermented creamer
