Yeah... there's no way this is fake. Even actors wouldn't be interested in acting this one. The guy on the left who gets attacked second gets shoved forcefully into the cubicle wall. The whole thing falls over. Even the monitors don't look like they're fake and i'm pretty sure the girl across from him gets hit because she flew back pretty quick too. And to all the people saying that they wouldn't stand around while this happened and that they wouldn't let some guy do this, think of it this way: noone expects to get hit with a monitors and various other office equipment at work - the first thing you're gonna do is be shocked, not be interested in fighting, least of all if it's someone you work with. Someone you might even be on good terms with.
