Actor Paul Rudd's character in the new Judd Apatow flick "This is 40" loves him some Sprinkles cupcakes, eating them throughout the film. For Washingtonians, that means that the Georgetown location of the store will be offering those very same cupcakes at a reduced price. Folks who come into the D.C. store next week can get a free cupcake if they buy one cupcake and say, "This is 40" to the cashier. It's what Sprinkles calls a "whisper word," but we're told you don't actually have to whisper it. The promotion lasts from Monday through Wednesday of next week and will also be valid that Friday, Jan. 11.
