Nasrudin took a job as watchman. His master called him and asked whether it was raining. I have to go see the Sultan, and the dye on my favourite cloak is not fast. If it is raining, it will be ruined.
Now, Nasrudin was very lazy; and, besides, he prided himself upon being a master of deduction. The cat had just streaked in, soaked through.
Master, he said, it is raining heavily.
The master spent some time getting himself arrayed in other finery, went out, and found that there was no rain. The cat had been soaked by someone throwing water at it to start it away.
Nasrudin got fired.
