I dont see a pizza man in this picture. And AAAAHHHH! Thats a very scary thought, bound that way to be just inches from saving yourself. Why would anyone DO such a thing??
in this situation one of three things happens you panic and drown, adrenaline kicks in and you now have enough strength to force your arm to dislocate and you can reach the drain, your to far away no matter what and it only looked as though you could reach it and you drown
There might be a pump in the drain activated when the plug is removed. That's the only reason I can see why that would work & why there are no other visible plugs in the area, otherwise having the ONE plug in the first place for draining would be uselessly infeasable. I really think of random whateverness when I see this image because of that (practicality is the grounds of common sense, some I am told to need & discover =P)
