Ach, this is now far enough in the distant past to revive the memory. Absolutely true: after a heavy evening of drinking, in the last bar I made eye contact with a girl who'd clearly also been heavily drinking. We met up. Clearly a "6-pinter", and I was probably in the same category as far as she was concerned, but we started chatting. While we were talking I was so drunk that I could hardly focus on her, and I noticed that she seemed to have similar problems. But we got on well, and eventually went back to my place. During our goings on, she said that she wanted to take a closer look at "it". I gave her the go ahead, then watched in speechless astonishment as she pulled her right "eye" out (it was artifical!) and held it closer.
My speech was already slurred due to the alcohol, but I think that was the only time I've ever been reduced to what must have sounded like a gibbering, inarticulate village idiot.
