A woman called to make reservations, "I want to go from Chicago to Hippopotamus¹（河马）,  New York" The agent was at a loss for words. Finally, the agent said "Are you sure that's the name of the town?" "Yes, what flights do you have?" replied the customer. After some searching, the agent came back with, "I'm sorry, ma'am, I've looked up every airport code in the country and can't find a Hippopotamus anywhere. The customer retorted, "Oh, don't be silly. Everyone knows where it is. Check your map!" The agent scoured² a map of the state of New York and finally offered, "You don't mean Buffalo((布法罗，又称水牛城), do you?" "That's it! I knew it was a big animal!"
