When camping and you have to take a crap, you walk into the woods and find a small tree (preferably Birch). You climb up the tree until it starts to bend over. When it is about half way, you mount your legs on the main part of the tree while holding onto the rest. Then you slide your pants down and take a dump from about 4' in the air.
Man, I have to take a crap. I am going monkey bending in the woods...
