no actual video or proof (just like everything else he says) but suckhisownmuscle has knocked-out a bear, wolverine, gorilla (well got a draw), and even one of the cheerleaders at his school. His training as a Seal, Beret, Delta Force, FBI, French Foreign Legion, Boy Scouts, Indian Guides and watching Rambo every morning when he gets up has made him into a unstoppable killing machine. He is the man! I hear it all the time.......... even though it is always from him.
