Getting what you pay for but not what you hope for is also known as the cobra effect. During colonial rule in India, British officials came up with a plan to reduce the number of dangerous cobras in Delhi. They offered a bounty for every dead snake. Over time, more and more dead cobras were delivered. It turned out that some people started breeding cobras to cash in on the program. When the British caught on and canceled the bounty, the snake breeders released their now-worthless cobras, thereby increasing the danger to everyone.
