For co-host @chadsmart, 1997 is a blank spot in terms of pop music. Co-host @MikeDeKalb, tries to fill in the void of Chad's memory with the suggestion of examining a song that stayed on the American Top 40 chart for nearly seven months.  British singer Mark Morrison hit it big in the summer of '97 with the catchy song "Return of the Mack."  While Morrison had better success in England with his other singles, "Return of the Mack" is his only hit in the States.  On this episode of Wonder Why, chad and Mike examine the Mark Morrison's debut album and life choices to try and understand why he remains a One Hit Wonder.
