People asked Mulla if he had ever met anyone stupider than himself. "Yes," Mulla said. "I hired a carpenter to build a door for my house. He didn't have a measuring tape, so he just spread his arms wide to measure the doorframe. Keeping his arms perfectly stiff, he walked out of my house to go back to his workshop. But he wasn't looking where he was going and fell straight into a shallow well. "People gathered around and yelled down, 'Reach your hands up so we can pull you out!' "The carpenter yelled back, 'I can't move my arms, I'll lose the measurement of the door! Grab me by the beard!'"
