Some of those are tough to watch. Same with "Monsters Inside Me".
The craziest thing I ever saw was on an "Untold Stories..." episode. A guy was out trimming trees/shrubs, fell, and landed right on the trunk of a shrub/small tree. It went straight up his rectum, and there was maybe 8 or 10 inches still sticking out of his body when they wheeled him in. There was a little leaf on the part that was sticking out, and I'm not going to lie to you, I giggled at first glance before I found out the extent of what this guy endured.
The trunk pierced <whatever it would have pierced> and extended all the way up to his heart! It managed to miss all of his organs, and the jagged end of it missed his heart by mere centimeters. They had his whole torso completely opened up, and when they were done cutting out/removing all of the tree, they literally rinsed his innards out by tossing bucketloads of water into him, hoping to wash all of the debris away.
As you might imagine, the recovery was long and excruciating, but he made a full recovery with no secondary infection. Can you imagine that?
I love to tell that story. There aren't many things you watch anymore with your mouth agape in astonishment, but that was one of them.
