Is the monkey's ass red or green?

The monkey's ass is red because there are many blood vessels on the monkey's ass, revealing the color of blood, so the monkey's ass is red. Long ago, monkeys and goats were neighbors. Goats are warm-hearted people and like to meddle. Monkeys often accuse him of saying, "Brother Yang, don't mind your own business, understand?" "One day, the two of them went out to play together. The monkey walked in front and the goat followed. Walking, suddenly a small Mars flew from one side and burned the hair on the monkey's ass. At this time, the goat said to the monkey, "Brother Monkey, should I take care of things that have nothing to do with myself?" The monkey casually replied, "you don't have to ask, of course you shouldn't care." "Well, that I don't care. "The goat said he didn't care, but he felt guilty, so he grabbed the monkey's shoulder and asked anxiously," Brother Monkey, things have nothing to do with himself, but they are harmful to others. Shouldn't you care? Hearing this, the monkey said impatiently, "You, you. The trouble with meddling is that you can't change it. " So they walked on. Soon, the monkey felt his ass hot. He looked back and said, "Wow, it's terrible, it's on fire, it's on fire." Just then, the fire grew bigger and bigger, and he cried out in pain. "Ouch, ouch. Goat! " "Responsible, responsible, responsible." Although the fire on the monkey's ass was put out by the goat, it left an ugly red mark the size of a palm. Since then, the monkey's ass has turned red.
