Mulla got a job as a carriage driver. One day, he drove his boss to a rough part of town. The boss warned him, "Keep your eyes peeled, this neighborhood is full of thieves," and went inside a building. A few minutes later, the boss peeked out the window. "Is everything okay? What are you doing?" Mulla said, "I'm just sitting here wondering... when a person stands up, where does their lap go?" A half-hour later, the boss checked again. "What are you doing now?" Mulla said, "I'm wondering... when I open my hand, where does my fist go?" The boss bragged to his hosts, "My driver isn't just a driver, he's a philosopher!" Another half-hour passed, and the boss yelled out the window, "What are you wondering about now?" Mulla replied, "I'm wondering who stole the horses."
