You don’t know how, but you have suddenly come face to face with what seems to be a queer British alien who has parked his spaceship nicely on your backyard. He emerges from his spaceship in a beam of light

Ziggy: Well hello there, human! I am Ziggy Stardust, here to save your planet from its total destruction in 1977!

He notices your weird glare.

Ziggy: …What? It is 1972…right?
