Mulla returned from a long trip with a mountain of heavy luggage. He flagged down a horse-drawn carriage at the station. "How much to take me and my bags to my house?" Mulla asked. The driver said, "It'll be five dollars for you, but I won't charge you anything extra for the bags." Mulla smiled brightly. "Perfect! Take the bags to my house. Since I cost five dollars, I'll just walk."
