Why is Elvis Crying?

I walk by this mural near Pioneer Square every day. And I always wonder, why is Elvis crying?

1. Maybe he was bitten by bed bugs at Heartbreak Hotel?
2. Guilt over being the King of cultural appropriation?
3. He just discovered how much Col. Tom was ripping him off?
4. He just re-watched his movie “Harum Scarum?”
5. Carl Perkins stepped on his blue suede shoes?
