I have the privaledge of calling Richard "Army" Maguire my friend, but he is much more than that. Army is has an amazing mind for the martial arts and knack for developing tools to make you a better martial artist. He is also an amazing athlete and has incredible hand strength. I have seen him shatter concrete blocks with his hands and tear decks of cards and phone books as well... if Army gets his hands on you pain is sure to follow! :)
The following video shows Army tearing a 2000+ page phone book in half:
