I can tell you what did not work, and that is thinking of the song you dislike the most, because then you get that one stuck in your head, so if you don't want the banana splits song swimming around and wiggling here and there in your ear, do not by any stretch of the imagination try and recall any part of the banana splits show opening song. trust me you will hate it almost as much as that Kodachrome song, and then it will pop into your head every time you see ketchup for some silly reason.
