Roman emperor Caligula was known for his jokes. Once, during offering the victims, he was given a hammer to stun the animal. The priest standing next to him waited for this moment, then to cut the animal’s throat. Caligula, however, suddenly burst into the head of the priest who lost consciousness.
Naturally, the emperor burst out laughing, treating it as a great joke. The rest of the priests, for fear of the unpredictable ruler, also began to laugh.
