Bowling alley proprietors in Connecticut invented ten-pin bowling. In 1841, there was a lot of crime at the nine-pin bowling centers that were popular then, and to end the problem the Connecticut legislature banned "bowling at Nine Pins." The proprietors added a tenth pin to get around the ban. For some reason the legislature didn't go back and ban "bowling at Ten Pins."
