real or fake?

i came across this gif yesterday (don't ask me how) but every time i watch it, i can't help but be a little mesmerized and perplexed on whether it's fake or not:



why do i question the validity of this gif?  Watch closely as the girl gets hit by a flying stop sign and think to yourself.  you just got hit by a stop sign, why are your arms not flailing everywhere, hair thrashing in the wind, mic flying in the air and wires all over the place.... she goes down like a tree!!!! does anyone else not find this a little odd?  she gets hit, holds on the mic, and if you maybe look a little closer she still looks like she's reporting the news...  the way she falls.... just seems unnatural... i would expect at least this kind of reaction:
