"The Hotel Suite" joke

Three guys went on spring vacation and booked three rooms at a
hotel. When they got to the hotel the clerk said there were no
reservations in the computer for them but they had an opening in
a suite they had.

So they said okay.

Then the clerk gave them the key, said it was on the 30th floor and the elevator was broken so they would have to use the stairs.
They said okay and made a deal the first guy would tell funny stories the 1st ten flights.

The second guy would tell scary stories the 2nd ten flights, and
the third would tell sad stories the last ten flights.

So the first told stories and they walked slow.

Then the second guytold stories and they sped up when they got scared.

Last the 3rd guy told sad stories and at the last stair he said, "Want to here the saddest story in the world" and the other guys said okay tell us.

He said, "I left the key in the lobby."
