A woman called a travel agency to make a reservation. "I want to go from Chicago to Hippopotamus, New York," she said.
The agent was puzzled. "Are you sure that's the name of the town?"
"Yes, of course," the customer replied. "What flights do you have?"
After searching the system, the agent returned. "I'm sorry, ma'am. I've checked every airport code in the country and can't find a 'Hippopotamus' anywhere."
"Oh, don't be silly! Everyone knows where it is. Check your map!" the customer retorted.
The agent scoured a map of New York state and finally asked, "You don't mean Buffalo, do you?"
"That's it!" the woman exclaimed. "I knew it was a big animal!"
