The expression “Elvis has left the building” has been used as a comedic and colloquial way to say “the show's over”, “get out while the gettin's good”, “you don't have to go home but you can't stay here”, etc.
Our aunts and uncles say it, our grandparents said it before it was cool, and little kids say it even though they don't have a clue who Elvis Presley is, but where did this fun expression come from?
Simon Whistler of Today I Found Out explores the origin of this saying that's more popular than Presley in this fun factoid video, getting to the bottom of this mystery with a little help from our friend Eddie Deezen.
