Hot joke: Why is the monkey's ass red?

This is more like what Niu Wangmo asked! Princess iron fan can also do it! Sister-in-law teasing brother-in-law is not a big problem! Let's talk about one thing first and then the theme! A driver was driving very fast on the road when the red light suddenly turned on halfway! Brake suddenly! Look around, this is not a crossroads, okay? Looking up, it turned out to be a monkey hanging from a tree by the roadside! The ass is brighter than the red light? ..... Why don't you guess? ..... I seem to have spoken! According to legend, the Monkey King accompanied Pig Bajie to get married in Gaojiazhuang, and Mr. Gao's daughter Qian Pig Bajie was ugly! And take a fancy to the Monkey King, tease him with words, make Monkey Brother, who has always looked down on men and women, blush and have a thick neck! For shame, monkeys will change seventy-two times! A plan to heart, face and ass? Stand up. This is against dogma! Secular desire is the nature of heaven and earth! The Jade Emperor was furious! Let the Tathagata work, and the monkey's red ass will never change back! This let the Monkey King's descendants pass on to this day!
