The Umbrella

As Nasrudin and a friend walked, it suddenly began raining hard.

The friend noticed that Nasrudin was carrying an umbrella, and said, "Open your umbrella to prevent us from getting soaked."

"No," said Nasrudin, "that won't do us much good. This umbrella is full of holes."

"So then why did you bring it?"

"Well," explained Nasrudin, "I didn't really think it would rain today."
