One hot summer night, Mulla and his wife were sleeping on the roof when a clumsy burglar climbed up. Realizing the thief wanted to break into the courtyard, Mulla hatched a plan. Speaking loudly enough for the thief to hear, he said to his wife, "Hey, remember the other night when I snuck down to the courtyard without using the stairs?" "No," his wife played along. "How did you do it?" "It’s easy," Mulla said. "I just recited a magical incantation, grabbed onto a beam of moonlight, and slid right down into the yard." The thief, thrilled by this secret, decided to copy Mulla. He muttered some gibberish, grabbed at the moonlight, and plummeted straight off the roof, shattering his leg on the courtyard floor. Mulla turned to his wife and said, "Grab the lantern, let's go see who just dropped in." The thief groaned from the floor, "Take your time. As long as you know magic and I'm this much of an idiot, I'll be your guest down here for quite a while."
