One time in Vietnam we came into our firebase for a few days. One nite one of the guys on perimeter guard duty brought in a green pit viper that they had found climbing the rpg chain link fence in front of their bunker. They had killed it and put it in an old coffee can. We were playing cards and drinking a little that nite and the next morning i woke up first and was stumbling around about half asleep/half hungover and saw a can sitting on a shelf and got it down to look into it. I had forgotten about the snake from the nite before........i didn't need any coffee that morning.
