I have been trying to find the original expression (I seem to remember this from my schooldays) about fools and horses as the only beings having the privilege to be candid to kings/princes and go unpunished.
So far, I haven’t been able to find anything that even remotely resembles this. The only search results I get are references to the famous BBC-sitcom.
Am I completely mistaken then?
I would love to hear from you if anything might come up.
