In 1838, Massachusetts outlawed the sale of hard liquor, causing drinkers to find creative ways to buy and sell booze.
One entrepreneur set up a booth with a sign offering, for a small fee, a glimpse of an amazing striped pig.
Those who paid to enter found a glass of rum standing next to a painted clay pig.
The pig saw nothing, so the transaction was safe, and the expression “blind pig” was born.
That’s why a bootleg joint is called a “blind pig”.
