Is Clown Allison Janney the only non-terrifying clown the world has left? The Mom actress costumes herself as a kind of casual-glam Bozo in Rachael Yamagata’s new “Let Me Be Your Girl” video, directed by Josh Radnor, and if anything, it makes her more charming. Allison Janney’s not luring small children into the sewer or lurking around in the woods near an elementary school. You can be sure of that. Okay, her seductive stare directly into the camera is … pretty intense, but still, better than every other clown in existence.
