Three writers, Sam, Pete, and Chuck, who were attending a writing convention, booked a room on the 75th floor of a hotel.
When they arrived back at the hotel from the convention, the receptionist told them, "I'm terribly sorry, but the elevator is broken. In the meantime, you will have to take the stairs."
Now, Sam was a writer of funny stories, Pete was a writer of scary stories, and Chuck was a writer of sad stories. The three of them agreed that, to make it less boring, Sam would tell the other two his funniest stories while they climbed from floors 1 to 25, Pete would tell his scariest stories from floors 26 to 50, and Chuck would tell his saddest stories from floors 51 to 75.
They started to climb the stairs, and Sam started to tell funny stories. By the time they reached the 25th floor, Pete and Chuck were laughing hysterically.
