the phrase "Buy Some Apples" originated from an abridged series of the cartoon My Little Pony Friendship is Magic, "Friendship is Witchcraft", & during episode 4 of the series , "Cutie to the Hip", the character Apple Bloom kept on saying on & on to her customers "Buy Some Apples", & after the scene she went to her friends Twist home, where a censor said "Buy Some Apples" as she was saying a phrase,
that type of Censoring from that series got so famous, it made lots of fan-censoring to fans to show censoring to the original series

However in the 6th episode of "Friendship is Witchcraft", it was remade, do a storyline about the Dole corp. owning the rights to apple to everytime someone said apple, it was replaced by another food, for example: "Boy, I sure do love this CHERRY.", it also had done the "Buy Some Apples" meme as well, & ever since then most of the fans did the same technique as in the series for their videos.
