A similar thing happened to me, many years ago. I was at a board meeting and talking to a circle of directors during a meal break when one of them noticed that I was wearing odd shoes. One was plain black while the other (also black) was a brogue......... how embarrassing! I must have gotten dressed it the dark that morning.

Years ago, the firm for whom I worked loved to have t-shirts with their logo printed on, and give them to the staff. When I received a certain one, I proudly wore it into work the next day...only to be told by the young despatch boy...I had it on back to front! :red:
