While Gardner did spin routines based on a wide-ranging social freedom, some of his material did play off racial stereotypes of his time. Often, he had African-American characters in his routines speak with an exaggerated, high-pitched, Butterfly McQueen-style accent in style of Flip Wilson, as in "The Motorcycle Story." In another of his routines, a black woman exclaimed, "James Lewis, git away from dat wheelbarrow -- say, you know you doesn't know nothin' 'bout machin'ry!" Although Gardner's early-1960s albums for RCA Victor contained questionable racial humor, there is nothing like the overtly racist content of his late-1960s act.
