Airbus?

A little old lady missed her flight. The agent who took the call was having a hard time understanding what it was she was asking about. She wanted to know why she never got picked up. It seems when she booked the flight the agent had told her the plane was an Airbus, which is a type of aircraft. She thought it was a bus. A bus that would pick her up at her home and take her to the airport. Of course, she missed her flight.
