Which studio head ...

          ... punched a celebrated comedian on the nose last night at a Los Angeles hotel?

          It seems that the studio head, whose strength was honed heaving scrap metal in Nova Scotia, Canada, took offence to some disparaging remarks made by the comedian (who is terribly popular, even if he isn't fond of our American custom of bathing) about his ex wife, an actress (though I use the term loosely) currently contracted to the studio run by our chivalrous maybe-Canadian, and knocked the comedian down.

           It caused quite the stir though by the following day had been hushed up and everybody present was denying it ever happened.
          Guesses?
