Whether or Not Andy Can Harmonize (Number 34 of The Things Nick is the Keeper Of)

Andy Cortez is often in the habit of launching into all sorts of musical ditties when in the presence of one Nick Scarpino with his voice and guitar. But talented and motivated as he may be, the fact of the matter is that he is not the keeper of whether or not he can harmonize when he does so - Nick is. And Nick will most likely decree that no, Andy cannot harmonize - but this is most likely said not because of a lack of musical talent on Andy's part, but because it increases Nick's ketone concentration if he upsets Andy.
