We don't really know too much about sumo wrestling, but that didn't stop us from enjoying the hell out of this video anyway!

In the clip, two big sumo dudes are going at it in the ring.  Right off the bat, one guy delivers a fierce forearm right to his opponent's head.  Now you'd just assume that these guys, because of their massive size, are tough as nails.  And in most cases they probably are.  But this dude has his bell rung so hard that he was really struggling just to stand back up!  He tries and fails.  Tries again, fails again.  And then finally fails for a third time.

Check out his struggles below!
