Why are there so many jokes about white rabbits?

A long time ago, the white rabbit was a very clever little animal in the forest. They like playing and joking, and sometimes they like playing tricks on others. They can beat animals older than themselves, such as lions and tigers. Those fierce and clever animals felt humiliated and had a bad feeling, so they created many jokes and stories about the little white rabbit being bullied to show off their strength and wisdom. So it continued to develop, and the white rabbit was abused and bullied.
