If you are attacked by someone you have to know how to defend yourself.  Your attacker might have a knife or a gun.  Watch the video and make sure you are good to go in case of an attack.  Or not....

Ok so maybe the video isn't exactly the best for showing you how to defend yourself, but the kid is pretty cute!  I couldn't think of a better way to learn how to defend yourself from a knife wielding toddler.
