Remake of an old video, but still looks painful. I believe I would be chasing him down and beating the crap out of my brother for that. Of course after I recuperated
I don't like to use conventional weapons in a retaliatory situation like this action calls for. I would go to tactical nukes such as superglue applied to certain body parts while the instigator sleeps. Let him know that you're willing to accept colateral damage and he'll never do something like this again.
If he would have made it into the bucket that should have been there, his berries wouldn't have gotten hit. Fail on his part.
BTW, I'm not a fan of pranks, so everyone involved in that would have gotten it 10x worse when they least expected it. Except for the little brother...His head would be bouncing off of that big log immediately.
