A turkey was chatting with a bull. "I would love to be able to get to the top of that tree," sighed the turkey "But I just haven't got the energy."
"Well, why don't you nibble on some of my droppings?" replied the bull "They're packed with nutrients."

The turkey pecked at a lump of dung and found that sure enough, it gave him enough strength to reach the first branch of the tree. The next day, after eating some more dung, he reached the second branch. Finally after a week, there he was proudly perched at the top of the tree.

He was promptly spotted by a farmer, who shot the turkey out of the tree.

The moral of the story: Bull shit might get you to the top, but it won't keep you there
