One famous strike of scimitar

Wisdom is constantly fitting your actions to your means not to your dreams. This reminds me of a story:

At the coffee-house, everybody was bragging of their military exploits.

“And you?” asked one turning to Nasreddin.

“I? One day, on the battlefield, I cut an enemy’s leg with one strike of scimitar.”

“Why not the head, as other people do?”

“That was impossible. Someone else had already cut the head.”
