My husband and I were having dinner in an outdoor cafe with Mark, an old friend of his who is a psychologist. While we were eating, a guy came up and said hello to Mark. Mark said, "Oh, hi, the blue jeans fit fine." The guy looked a little puzzled and went off to sit at a table nearby.

A few minutes later, Mark suddenly went into a fit of giggles, explaining that he had thought the guy was the salesman who had sold him a pair of jeans earlier in the day, and he had been worried about the fit. He had just realized that the guy was in fact a patient he had been seeing, who had just been released from the looney bin that morning. So of course the first thing that happens to a just-released pyschiatric patient in the outside world is that he runs into his shrink, who makes a totally nonsensical statement that sounds like a secret code. To make matters worse, we all started giggling and couldn't stop, and every time we glanced at the guy, it got worse. I never did find out if he checked back into the nuthouse after dinner.
