A mere bagatelle my dear

Posted by Bookworm on November 12, 2004

The radio announcer was reading a commercial involving bagatelles and then ad libbed: "it's a mere bagatelle my dear". Is this a famous line from a play or book? Or, is it just a phrase? An admittedly quick Google search didn't give me a source. It did, however, confirm that this phrase is indeed used to denote a trifle.
