Method Man -- The Explosive Shot to the Face

8/19/2010 8:00 AM PDT
TMZ has obtained video ... of the moment some dumbass at the Gathering of the Juggalos fired a beer can at rapper Method Man -- striking him in the face and opening a pretty nasty wound. 

As we previously reported, Meth plans to "sue the motherf**kers" responsible for the incident -- but he was unclear if he will go after the event organizers or the person who tossed the object.
