This has to be one of the funniest things I have seen all week! The Slow Mo Guys are back at it. One of them climbs into a giant water balloon, and they proceed to fill it. The comments as they do are hysterical, and of course the one in the balloon develops an itch on his head that he can't scratch! Wait until you see the balloon pop in slow motion after it's filled to capacity! I have a feeling you'll be like me and watching this over and over again!
