About 20 years ago, I worked with a man who spoke like this. It had to be some kind of a birth defect, but every single day, he spoke "spoonerisms!" I would hit the floor in laughter, and he would be offended. It took months, on my part, to realize that he was for real. These were not contrived jokes. He didn't know the difference. On the one hand it was somewhat sad (as he didn't get it) and on the other hand, it was really amusing! CHEERS, Bob
