In the early day of Windows 3.0 I met Bill several times. Once, at a journalist's dinner, he and I both went to the men's room at the same time. While Bill was doing the business I was struggling. To my embarrassment I discovered I had put my boxer shorts on back to front.
"Having trouble with your underwear, Michael?" quipped Bill.
"Not as much trouble as your having with your software," I retorted.
We never spoke again.
