In the OP, number 20, the one about "rule of thumb," is bogus. It was hatched up sometime in the 1950s or 1960s by someone like Gloria Steinem or Germaine Greer.

On most adult, the distance between the end joint of the thumb and tip is almost exactly an inch, and carpenters and tailors used to use it for making rough measurements. I have big hands, so mine is more like an inch and a quarter. But knowing that, I can still use it to make approximate measurements if I don't have a ruler handy.

Burple is the color of a belch.

Did you know that ping-pong spelled backwards is gnop-gnip? (It's funnier when you say it.)
