I have seen that before. Very funny. Webby you think it is fake?
Indeed, very fake. Aside from the deflation issue, the inflation is much too slow, there's no "debris" from the airbag, the sound isn't natural, the man's reaction is too mild, the woman looks far too stereotypical, and the "sleeping-startled-awake" thing is both horribly cliche in comedy routines and overacted on her part.
