One time when I was in the Army stationed in what was then West Germany , we were camped at the edge of a small wooded area . We had been told not to bring or keep any food in the tent . My tent mate did not listen , and left an empty can of spam on the ground when he went on guard duty . So , let ' s set the scene . It ' s the middle of the night , and I am sleeping alone on the tent when I am awakened by loud grunting sounds . I blearily open my eyes , and see that a huge boar hog is standing in the tent , licking the empty spam can . I was never so glad that the tents in the Army don ' t have attached floors . I rolled off my cot and out under the tent and took off running in just my tighty whiteys . <| sep |> Bad joke . Rex started McCoy when he wasn ' t ready and he reinjured himself .
