One night, Cuvier’s students decided to play a trick on their professor.
They dressed up in devil’s costumes and woke up Cuvier in the middle of the night, chanting, “Cuvier, Cuvier, we have come to eat you!” Cuvier opened his eyes and took a good look at his pretend attackers.
He said, “All animals with horns are herbivores (plant eaters). You cannot eat me,” and went back to sleep.
