Future Twit: Shower - Shampoo Prank

I had to laugh when I found this video of a rather juvenile but very funny prank that takes place after some sort of visit to the swimming pool. Watch as a young kid keeps getting tricked over and over by an older boy where the older boy keeps putting extra shampoo into his hair.

I'm not sure whether the video is a fake or not. To me, it seems like the kid should have noticed the extra shampoo in his hair. I think that he could probably feel it, if nothing else. Also, the kid in the shower should have noticed the older boy walking up behind him because of peripheral vision. But, it's still an enjoyable video.
