Phrase Finder Rules OK

Can also be "Phrase Finder Rules, OK?"

Where did this come from? Who was the original person who Ruled OK? Or did they rule U.K.? I've always wondered about that.

Do you mean ending sentences with "...OK?" Like the school counselor Mr. Mackey on South Park "who has a very big head and ends virtually every sentence with his signature phrase, 'M'kay?'"

There's a specific construct I've seen many times, always like "[noun or person] rules OK", or sometimes with a comma and a question mark "[noun or person] rules, OK?" The most recent example is a headline of an article in the latest issue of The Economist "Primogeniture Rules, OK?" next to a photo of two siblings feuding over who should be in charge of their late father's multinational conglomerate.

I've seen this time and again. I thought it would be familiar enough to our friends across the pond.
