This must be one of those 'Can you spot it?' videos because apparently there is ultra slow-motion footage of a balloon being popped - I've watched it a thousand times and can't see any balloon or popping going on :)
I've heard of 'get them while they are young', but this is pretty weird. The expression "What The F*ck" was made up for videos like this. Seriously what the hell is wrong with people these days, totally insane.
