Tell me some jokes about cows. I thank you ~ ~

Cows and bulls lived for a long time. The cow felt that life was boring, so she left the bull to find the elephant. After a while, the cow felt that the bull was still good to her, and it was meaningless to be with the elephant, so the cow returned to the bull, but the cow found that the bull didn't seem to be as good to her as before. So the cow asked the bull, dear, why are you lukewarm to me? Have I changed, or have you? The bull said, of course you have changed. "What has changed?" The bull looked at the cow and said, "You are bigger than the cow."
