I've carried many dead deer out of the woods solo. Not so much a party trick, but man, functional fitness at its finest when throwing a couple hundred pounds of dead weight over the shoulders and hauling it a 1/2 mile.
If you are wondering how I get the deer up to the shoulders - I tie the legs together with 2 ropes , and do a squat from the bottom position holding the rope over my shoulders. Once the deer is about half way up my back, I just jump (its almost like a clean but from the back!) and have the deer across my shoulders.
