The least we should be able to ask of the news media, since they obviously can’t be trusted to report the news competently, objectively or fairly, is to not make the public more stupid and ignorant than it already is. CNN’s Carol Costello, a prime offender in the incompetent and biased, can’t even clear this low bar.

This morning, as the networks interrupted their around the clock Robin Williams death coverage to note the passing of famed screen siren Lauren Bacall at the ripe old age of 89, Costello led her report by referencing Bacall’s “beauty, talent, and wit.” Her wit was represented by a clip of her famous line as “Slim” in “To Have and Have Not” (1944):

“You know you don’t have to act with me, Steve. You don’t have to say anything, and you don’t have to do anything. Not a thing. Oh, maybe just whistle. You know how to whistle, don’t you, Steve? You just put your lips together and… blow. “

But this quote has no relationship at all to Bacall’s wit, and she was indeed witty. The line was written by Jules Furthman, or perhaps William Faukner, both credited with the screenplay, inspired by Ernest Hemingway, who wrote the novel and created the character Bacall was playing. A seven-year-old could have been just as witty, with these guys putting words in her mouth.

Incredibly, a ridiculous number of people really think actors are responsible for the lines they say on stage or on screen. This is, you’ll agree, idiotic and an embarrassment, and CNN should not be encouraging such a misconception.

And yet it did.
