One sunny day, a little white rabbit went out to play and forgot the way home. He walked sadly and met a little black rabbit at a fork in the road. He asked, "Little Black Rabbit, which way should I go home?" The little black rabbit replied, "Let me do it, and I will tell you." "Then the little white rabbit made it for the little black rabbit, and the little black rabbit told him to go the first way. Then the little white rabbit walked and walked. At a fork in the road, he met a little red rabbit. The little white rabbit asked the little red rabbit, "Little red rabbit, which way should I go home?" Little Red Rabbit said, "Let me come and I'll tell you." The little white rabbit made it for the little red rabbit, who told it to go the second way. Later, the little white rabbit finally went home and gave birth to a little yellow rabbit.

I would like to ask: "Why did the little white rabbit get fucked by the little black rabbit and the little red rabbit, and a little yellow rabbit came out as a result?" Not other colors? Tip: "Remember it's a brain teaser, and the answer is super funny. Answer: I'll tell you as soon as I finish it.
