Once there was a young cock that was trying to fly high like the eagle. After many attempts, it was only able to reach the lower branches of a big tree.
A bull happened to come by. It saw what the cock was trying to do. " Hey! Cock, since you do not have the strength to fly high, why don't you eat some of my shit? There are very nutritious. I am sure that after taking them you can fly high."
The cock thought for a while and agreed to give it a try. So the bull pooped out some shit whereupon the cock ate them. After some time, the cock felt very strong. With its first attempt it was able to reach the top of the tree. It felt very proud and gave out a long and loud crow.
A hunter who was nearby got attracted by the loud crow of the cock. He quickly took aim and shot the cock down.
That's how bullshit can propel you to the top, but it will not keep you up there.
