A great many years ago, a couple of Jehovah Witnesses bit off more than they could chew with my grandmother. During the unsolicited conversation one of them remarked, "Only God can make a rainbow". To which my grandmother-who was watering her plants at the time-said, "Nonsense!", and created her own rainbow with a spray of water from the hose. Family lore has it that was the end of the conversation.
