"Why don't you nibble on my droppings?" replied the bull. "They are all packed with nutrients."
The turkey pecked at a lump and found that it gave him enough strength to reach the bottom branch. More dung later, and he was proudly perched at the top.
Soon he was spotted by the farmer, who shot the turkey out of the tree.
Moral of the story: bullshit might get you to the top, but it won't keep you there.
