Mullah Nasrudin and the Key

Mullah Nasrudin is one night looking for something next to a lamp post in the street.
A friend is going by and asks what he’s doing. The Mullah says, “I’m looking for my key which lost.”
The friend decides to help and searches the ground under the lamp post. Half an hour later the friend asks,”Are you sure you dropped your key here?”
Nasrudin replies, “Oh no I lost it inside my house in my bedroom.”
The friend screams, “Why in hell’s name, are we searching here?”
Nasrudin smiles and says, “There much more light here.”
