wow - what a great pun!!!!! ..... "tromp loray" would be "trompe l'oreille" or "to deceive the ear"

Oh, Rod thank you for that! Being 50 percent deaf I learned that phrase early in my High School French.... been waiting to use it, in context, since I signed on here! Don't expect more, as I love puns but am, in general, wretched at them.
Is "trompe l'oreille" in the French dictionaire as an explanation for Mondegreen?
