just for laughs

Bill, Jim, and Scott were at a convention together and were
    sharing a large suite on the top of a 75 story sky scraper.
    After a long day of meetings they were shocked to hear that the
    elevators in their hotel were broken and they would have to climb
    75 flights of stairs to get to their room.  Bill said to Jim and
    Scott, let's break the monotony of this unpleasant task by
    concentrating on something interesting.  I'll tell jokes for 25
    flights, and Jim can sing songs for 25 flights, and Scott can
    tell sad stories the rest of the way.  At the 26th floor Bill
    stopped telling jokes and Jim began to sing.  At the 51st floor
    Jim stopped singing and Scott began to tell sad stories.  "I will
    tell my saddest story first," he said.  "I left the room key in
    the car!"
