Why is the monkey’s butt red?

1. The real reason: There are many blood vessels in the monkey's body, and blood flows to different parts of the body through the blood vessels. There are particularly many blood vessels on the monkey's butt, and the color of the blood is revealed, so the monkey's butt becomes It's red. 2. Joke: Legend has it that many years ago, a monkey and a crab were good friends. One day, the two of them were walking in the forest and saw a jar of honey on the ground. Both wanted to eat, but the monkey wanted to keep it to himself. So he rolled his eyes and came up with an idea. He said to the crab: "Let's go to my house!" "Okay." The crab agreed and followed the monkey back home. The monkey's home is in the tree, and the crab is dragged up the tree by the monkey. The monkey entered the house first, followed by the crab. As soon as he entered, the monkey put the crab into the bucket and put it on the ground. Then he sat on the bucket and ate the honey. The crab was very angry, so he used his pliers to cut a hole in the bucket, and pinched the monkey's butt hard with two pliers! ...So, the monkey's butt became red from then on
