Yes, of course. You're right. Somehow I had forgotten about broccoli history. I don't know why. Like all Canadians, I took a broccoli history class in school when I was young. I still have my old text book "A History of Modern Broccoli".
Few people know that the expression "May a smile be your umbrella" is derived from the old expression, "May a broccoli be your umbrella". Back in the middle ages, broccoli was much bigger and people actually used them as umbrellas. Unfortunately, these large broccoli pieces were very heavy to carry around and many people got horribly injured in "broccoli accidents" when they got tired and dropped it. The mechanical umbrella was then invented and this usage thankfully died out.
It's strange to think that it was only in the computer age that broccoli's true usefulness was discovered.
