It seems that anything you say will offend somebody — sticking like a bone in their craw. All the more reason then for my making no bones about it (15thC.), “speaking frankly and without hesitation”.
Very little tickles people’s funny bone (19thC.) nowadays. It’s a nickname for the arm bone between the shoulder and the elbow, formally called the humerus. The ulnar nerve passes directly over that area, a good whack there resulting in a weird tingling sensation that’s peculiar or “funny.” That together with a pun on humerus, made for our funny bone which became “our sense of humor.”
You don’t have to whack folks on it to get a laugh, just rib them a bit. Anything goes as long as it’s not done with malice. Ribbing is nothing more than good natured teasing, from either tickling a person around their ribs, causing them to break into laughter or poking them there while telling a joke. In time, our funny bone should return intact. I intuit it, or feel it in my bones (17thC.), the same way persons with arthritis have an uncanny ability to predict the onset of rain due to their special sensitivity to a drop in barometric pressure. And that is the bare bones for today.
