Now that I have your attention ^^ I’ll deliver on the promise… but first I want to explain how I came upon it.
I was browsing the web (like ya do) and I came across this wiki about archaic, unusual and humorous units of measurement. It’s incredibly fascinating, and I highly recommend you check it out when you have a few minutes and a moment of curiosity.
I was a little ticked when I looked at the contents list and couldn’t find my (finish carpenter) aunt’s favorite measurement, the BCH (or blonde c**t hair) … then I found the link at the bottom-ish for hair as used in measurement.
Only problem… the person writing the article didn’t include BCH, just RCH (red… well, you get the idea). As a matter of fact, the article (and at least one reference) sez that noone EVER uses any other color of hair for the mesurement, just hair, c**t hair, and RCH. grr.
Otherwise, good article. and well worth reading, just for the interesting historical and cultural info. But darn it, they were wrong about that!
