Joe the turkey was chatting with Mark the bull.
"I would love to be able to get to the top of that tree," sighed Joe, "but I haven't got the energy."
"Well, why don't you nibble on my droppings?" replied Mark. "They're packed with nutrients."
Joe pecked at a lump of dung and found that it gave him enough strength to reach the lowest branch of the tree.
The next day, after eating some more of Mark's dung, Joe reached the second branch.
Finally, after a fourth night, there Joe was proudly perched at the top of the tree.
Soon he was spotted by a farmer, who shot Joe right out of the tree.
Moral of the story: Bullshit might get you to the top, but it won't keep you there
