“Although they had long known that Earth was about to be destroyed, their attempts to communicate this knowledge to humanity were misinterpreted as attempts to jump through hoops for bits of fish. They left the Earth just prior to its destruction, but left humanity one last message, a triple backwards somersault through a hoop whilst whistling the Star Spangled Banner when, in fact, the message was this:

“So long and thanks for all the fish.”

 

-Douglas Adams, Hitchhiker’s Guide to the Galaxy
