<P> Episodes of the series always open and closed with Kenan and Kel breaking the fourth wall by interacting with the studio audience, standing in front of a red curtain that is placed in front of the main set while they are still in character . A frequent running gag of the openings is Kel never knowing what the night's episode would be about and Kenan refusing to tell him . The closings would frequently feature Kenan coming up with a new scheme, often asking Kel to get various assorted items and meet him somewhere . Frazzled, Kel would exclaim his catchphrase, "Aww, here it goes!" </P> <P> Another catchphrase commonly heard throughout the series is "WHYYYYYYY!?!?", usually screamed by Kenan after Kel does something stupid . </P> <P> The theme song, entitled "Aw, Here It Goes", is performed by rapper Coolio . He is featured in the opening credits of the show along with Kenan and Kel . The lyrics describe the show and reference other famous duos such as Siegfried & Roy, Abbott & Costello, Penn & Teller, and former Los Angeles Lakers teammates Magic Johnson and Kareem Abdul - Jabbar, as well as Nancy Drew and The Hardy Boys . </P> <P> The series was created by Kim Bass (who also co-created the teen sitcom Sister, Sister). It was reminiscent of the classic comedic duo stylings of Laurel and Hardy, Martin and Lewis or Abbott and Costello (who were actually mentioned in the theme song), with Kenan being the straight man and Kel his comedic foil . </P>
