His answer to
What is the stupidest thing done by a Roman Emperor? is brilliant.
A lot of people don’t know this rare historical fact, but Augustus Caesar tried to kill all the ants in the entire Roman Empire.
Yes, Augustus was a great man. Yes, his public works revitalized Rome. Yes, he ushered in a grand imperial age, but, he also tried to kill all the ants. This was allegedly done in order to protect crops.
He gave cash prizes to anyone who would kill 50 ants. This actually caused the ant population to explode, because everyone from Brittania to Egypt and from Hispania Ulterior to Asia Minor started ant farms. The city of Rome was actually blockaded by thousands of ships carrying nothing but bags of dead ants.
Then Augustus knew he messed up. He immediately stopped paying people for ant corpses to prevent the empire from going bankrupt. All those ant farmers who had sailed to Rome now started to grind up their ants and pass it off as blackberry jam. They sold many jars and killed hundreds of people with the poisonous jam. Many of the ants were, in fact, still alive, which led to an ant infestation all over Italy.
Although he wanted to protect crops, he ended up doing the opposite as the explosion in ants resulted in all of the food being eaten. Millions died because of the ant fiasco. Fortunately, the Romans were just; Augustus was forced to run around the city of Rome completely naked for 3 hours as a punishment. He got a terrible sunburn.
