Three men worked in the Empire State Building on the 102nd floor.

One day the elevator was out of service, so they had to walk up to their office. To pass the time, they decided that one would sing a song, one would tell a joke, and the third would tell a sad story - each taking a turn every floor until they reached the top.

Finally, as they reached the 100th floor, one man sang his last song. As they reached the 101st floor, the second guy told his last joke. As they ascended the flight to the 102nd floor, the third man said, "I forgot the key."
