I have done that, when I was drunk. This is why I don't find it so strange. Heck, I once even left my wallet on the ground, because I took it out of my purse to look for my keys and then completely forgot to put wallet back inside. I was able to recover it in the morning, and was really lucky that it was still there. I am not proud of what I did, but it is a fact that I did it in my drunken state - and I am sure I am not the only one on the planet who did the same, or something similar. It also seems that there are contradicting statemets in the thread about whether the hat/glasses were found in the house outside, but that does not change much in my personal opinion. You can easily lose hat outside as well.
