Cover art for If I Had A Tail lyrics by Queens of the Stone Age

It's a song about Homme's old-self. In 2010, Josh Homme was legally dead for moment due to complications during knee surgery. Homme said that it gave him a different outlook on life and heavily inspired Like Clockwork. He's pretty much saying that his old-self could be mistaken for the devil if you gave him a tail.
