As lead singer and keyboardist of the funk band Nasty Delicious, Craig (Craig Robinson, "The Office") knows a thing or two about working the crowd, but his day job is where he really makes the grade. Every struggling artist knows the drill: You've got to pay the bills while you wait for that big break. So when Craig finds himself short on cash, he takes a job as a substitute high school music teacher. It's an easy gig, right? The school principal (Peri Gilpin, "Frasier") believes that rules were made to be strictly upheld. She's none too fond of Craig's unorthodox teaching style, or his crush on the pretty English teacher (recurring guest star Meagan Good, "Think Like a Man"). It's a constant struggle for Craig, having one foot in the music world with his band, Nasty Delicious, and one foot in the teaching world. But if Craig wants to get the girl of his dreams and teach these kids the joys of music, he'll have to buckle down, shape up and get the funk out. Mr. Robinson is inspired by Robinson's real-life experiences as a music teacher.
