Dude #1 (who looks like he is dressed to go swimming) tries to kick Dude #2's hand which is held up as a target.
Dude #1 accidentally kicks Dude #2 in the face. Dude #2 staggers to the ground.
Meanwhile, Dude #3 (also ready for a swim) decides that this is a prime opportunity to knee Dude #1 in the armpit for no reason whatsoever. Both fall down.
Dude #4 walks in from nowhere and declares victory.
Then Dude #2 finally gets up (still dazed) and tries to tackle the fence.
