I don't know. I always thought of a comedy song for the end of the world. Something by "Weird Al" Yankovic.
If the world ends by alien invasion: Slime Creatures From Outer Space.
If the world ends by explosion after you had a bad day: One Of Those Days.
If the world ends by nuclear holocost during the holidays: Christmas At Ground Zero.
If the world ends by computer virus: Virus Alert.
If the world ends on your birthday: Happy Birthday.
Then, people could enjoy the end of the world and possibly laugh at it.
