Actually the term "funny bone" has been expanded to include any bone that you might actually hit and it hurts (shins, forearms, knees, elbows, even head sometimes). But you're right...it's not funny, it hurts.
@comfi1 Thank you...actually, I don't know if that expansion is official, but most people I know or have known have said that whenever they hit any solid bony part so I'd say it's "unofficially expanded to include".🤠
