I can't remember what I said but whilst deep in conversation with myself early one morning on the way to work I made eye contact with a woman who was getting out of her car. I froze, her expression quickly changed to something I can only describe as an "I'm not getting raped today" face with a mixture of sheer terror and indignant anger, before she got back in her car and sped away. That one also shook me for a good few months, mostly due to her parting visage.

I find myself often coming out with "finger in the butt" or some variation (finger in your butt, finger up the butt etc) which is a bit weird as I'm English and don't use the word butt in normal conversation. Also, for some reason lately the "N" word in lots of permutations. It's not completely involuntary as I can control it when I need to but I'm not really consciously doing it when it happens either. Like you, friend, I think something may indeed be wrong with me and that it's time I have someone else check myself, before I wreck myself.
