I've done this before. I Jokely ordered it under the name "Sam Winchester" and my friend did the same under Dean, and it was funny and I got the water, the 7000000 spam letters after that were however not funny. They wont stop sending me crap mail. Also the holy water "bottle" is like .1 inch wide and like 1 inch long. SUPER SMALL.
But hey, now I can fend off a single demon, or at least make him say Ow.
WARNING: I don't actually execpt to be attacked by demons or believe that the show supernatural is real the above is a joke please do not take it seriously, exepct the junk mail and the size part take that seriously. Oh and I really did use that name.
