When I was in the military (Augusta Ga.) we went to school in shifts.......Vietnam area. I went from 3pm to 11pm............so in the mornings they would bust into our circus tents (temp barricks) to get us up for duties. We would all charge out to the porto-lets to hide out. The sarge would always start to tip it over to get you out........... and yeppers it worked everytime.........MAN!
