This time pertaining to mayonnaise. Even mayonnaise needs to rehabilitate its image now, for being just too damn white. After all, the joke was that Mayo was for White people, right? So here we see a mulatto, a disproportionate amount of negroes, a black dancing with a White woman, a black man draped around a White, and a disheartening lack of White men. Oh wait! There is one! Right under the vocal caption of "Don't be so Mayo," showing a "boring" White male, obviously a fan of mayonnaise! What a fuckin' dope! That prick loves mayo? What a prick, just like all White men!
Obviously, what they really mean is: don't be so white!
You decide, dear readers.
