Shmuel noticed his friend Avrum underneath a streetlight, searching for something on the ground.
“What are you doing, Avrum?”
“I’ve lost my keys. Please help me look for them.”
A while passed with no success.
“Avrum, where exactly did you lose those keys?”
“I lost them in that alley over there.”
Shmuel was dumbfounded. “So why are we looking here!?”

Avrum looked over at his friend: “Because the light is better here!”
