Query: The bottle of the thousand screaming dolphins

Yeah... So. Beautiful bottle. Nice weight. Like the loop on the top for attaching it to something. Good size.The only problem is that, when you drink out of it, the air vent makes a noise like a thousand screaming dolphins. This is NOT ideal if you are in a position where you must consume liquid in the presence of any other human being within earshot.
