But your eyes are flying saucers from another planet...

The line's a play on eyes like saucers/eyes as big as saucers = eyes opened very wide in surprise, shock or amazement.

Which is a surprisingly old expression, dating back as far as the 1400s! By the late 1500s, we already find eyes compared to silver saucers. In the 1600s, writers were using eyes as big as saucers and saucer-eyes much as we do now!

Now Taylor adds a sci-fi twist to it: saucers => flying saucers 🛸 => from another planet 💋
And they say wordplay is dead, eh?
