Well.......
Once upon a time, I was visiting the U.S. Air Force base at Karamursel, Turkey.
After a long evening at the Enlisted Men's Club, the only part of which I vaguely remember, is crawling on all fours along the road, laughing insanely, I awakened the next morning in a bunk, fully dressed and with the worst headache of my life.
I laid there, whimpering with pain, and seriously considering giving up alcohol for eternity.
About that time, the other guys I was traveling with returned from breakfast, the thought of which actually made me feel worse.
They informed me, that when we all arrived at the barracks the night before, I came through the door, located my assigned bunk, and charged towards it. Unfortunately, I was too drunk to stand erect, and was bent over at the waist. Even more unfortunately, the bunk was narrower than I was tall from the waist up. Therefore, in full charge, my head hit the concrete wall before I hit the bunk.
One of my companions was our corpsman, so he checked to make sure I still had a pulse and was breathing. He didn't think he could determine if I was brain-damaged in my current state, so they just left me for the morning.
Of course, we all returned to the Enlisted Men's club that evening, but that time I didn't get into a Martini drinking contest.
