there is zero chance that it's zero holes -.-
Edit: Aight, I am gonna dial back the frustration here and explain. I am looking at the from the perspective of 3d modeling and as a result there is only one hole, but the possibility of 0 doesn't exist, 2 is ARGUABLE, but still most likely wrong as the straw itself is a solid mass other than the through hole. if I were to model this in a 3d program there would ONLY be 1 hole, no more, no less.
