Oh, you like to sing? I was confused, because not only did you not win "American Idol" last season, but you're just making eating noises with your mouth in this commercial. Music blog Idolator rightly points out that this Zaxby's spot features everything about Melinda Doolittle except her value as a spokesperson: her singing voice!
BTW, if you're as confused as I was, Zaxby's is a greasy fast-food chain that operates in the Southeastern U.S. Think SNL's "Cluckin' Chicken."
