On the 60s-70s TV show, Endora put a spell on Darrin to tell the truth, much to the advertising executive's dismay, he tells the client that his product is disgusting.

Call it what you will, an angel whispering in the ear or a BS-detector, but when the liar-liar pants on fire starts talking, the Super-mom bells go off, it matters not if it's in person or on the phone...the game is afoot.
