Watch only if you have plenty of time to waste -- or -- if you're very busy.
If you don't have much time -- or -- if you're not really bored, this isn't funny in the least. If you're in a rush this will be offensive.
However, if you don't have much spare time and you have lots to do, but you're not busy at the moment, and you're looking for a diversion, but then intend to get back right to work -- this is really effing funny.
On the other hand, if you have a lot of time on your hands and wish you were busier, don't watch this.
If the above has confused you, do not watch the video -- you won't understand it. However, if the above makes perfect sense, you will almost certainly find this video rewarding. (If the previous two sentences confused you, you're probably easily amused, in which case the video is perfect).
If you're still reading this horseshit your break is over and you'll have to wait till later to watch the video.
If you feel I've wasted your time then this video will seem too high-brow. If you feel I haven't wasted your time, you're the type that gets taken advantage of a lot and the video will probably seem innocuous yet interesting.
If all this has pissed you off you will definitely enjoy this video. If it hasn't pissed you off, you won't care either way -- it's your call.
