Nasrudin and the lost key

One evening, Nasrudin was out near a sidewalk,
looking through the grass and bushes under the light of a lamp post.

A friend of his walked by and asked what Nasrudin was up to.
“I’m searching for my house keys,” said Nasrudin.

The friend offered to help, and the two spent a considerable amount of time
continuing to search under the light of the lamp post.

Finally, the friend asked, “Where did you last have your keys?”
“Oh, back at the house,” replied Nasrudin.

Exasperated, the friend shouted, “Then why are we looking here?!”
Nasrudin plainly stated, “Because the light’s better here.”
