Tale and moral

"There was a bird flying south for the winter, but he got caught in an ice storm and fell to the ground. He froze, but a cow came along and clapped on him. The warm poop unthawed him and he liked it, so much he started to sing. A cat came along to see what the commotion was about, asked if he could help, saw it was a meal and ate the bird. Herae are ther morals of the story. Everybody who shits in you ain't your enemy. Everybody who comes along to help ain't your friend. And if you're warm and happy, even in a pile of shit, keep your mouth shut. "
