If you need a good laugh today, this will do it.  Quite simple really, a woman walking along not paying attention to her surroundings and directing all of her focus to her cell phone, does not notice that the floor transitions into a pool.  She falls in, and seems rather upset that someone would construct a pool in this particular spot.  Seems a bit strange to me that the guys filming were just waiting for this to happen and then it did, was it staged?  Don't care, it made me chuckle.
