The little white rabbit got lost in the forest and met the little black rabbit, so he asked, "Brother Little Black Rabbit, how can I get out of the forest?"? The little black rabbit replied, "Make me happy and I will tell you." So the little white rabbit makes the little black rabbit very happy. So the little white rabbit walked and walked, but he got lost and met the little grey rabbit, so he asked the little grey rabbit, "Brother Grey Rabbit, how can I get out of the forest?" The little gray rabbit replied, "Make me happy and I will tell you." So the little white rabbit made the little gray rabbit happy again. The little white rabbit finally got home and gave birth to a little rabbit. Excuse me, what color is the rabbit born by the little white rabbit?

When your girlfriend asks you, you tell her "Make me happy and I'll tell you".
