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 haven’t gotten the energy”
“Well, why don’t you nibble on some of my droppings?” said the bull.
“They are packed with nutrients.”

The turkey pecked at a lump of dung and found that it actually gave him enough strength to reach the first branch of the tree.
The next day, after eating more dung, he reached the second branch.
Finally, after a fortnight, there he was finally perched at the top of the tree.
Soon, he was spotted by a farmer, who promptly shot the turkey out of the tree.

Moral of the story is:
Bullshit might get you to the top
But it won’t keep you there.
