Do you know a story with a terrible beginning, a funny middle and a tragic end?

Gay friends rented a room on the 50th floor to save money. Suddenly one day, the power went out, so I couldn't take the elevator, so I had to walk to the 50th floor. In order to avoid boredom, some people suggest telling jokes in turn to enrich boring time. When they reached the 49th floor, the joke teller in turn said, "I left my key on the first floor."
