Today, I was regaled with the story of a guy who bought two American Bullfrogs to get rid of the snakes that had infested his yard suddenly. He was incensed when he found one of the frogs dead the next morning from - not astonishingly - a snake bite. Still, I can't help but feel it would be really interesting to meet someone who thinks it's a great idea to pit some frogs against a bunch of metre-long fanged reptiles.
