some of the things on here werent very intelligentt but id have to say that this might have been the worst

maybe smoking underground in a mine, I went down in one(before I started smoking), pretty insane. Now think of rolling a very fat blunt with a couple of friends, go way underground, light it up, smoke it all and than finally realize you're half a mile underground!

im not sure where u live but most mines around where i live have flammable gasses
