Concord Litho is helping NBC with a promotion for an episode of My name is Earl. NBC is going to make people stick their noses in the stink delivered courtesy of TV Guide. Yes, during the May 3 “Laugh ‘n Sniff” episode, NBC will prompt viewers with on-air graphics to rub one of six corresponding numbered boxes on TV Guide’s scent card, which will release aromas connected to the My Name Is Earl storyline, including the smell of “a brand-new car,” and the chocolaty-creamy signature scent of Oreo cookies who is sponsoring the episode. The stinky ads will appear in the April 30 issue of TV Guide.
