Emperor penguin

Your voice is all detached on a radio-wave breeze
We have another caller with a bachelor degree
Talkin alien invasion as the only chance for unity
Well sorry to interrupt you caller
But that's a physical impossibility
That's a physical impossibility
That's a physical impossibility

You'd be tossed up or wash up
The narrator relates
In a Spartan Antarctican walk for many days
Meet with Emperor Penguin devotion to the egg
And their women are swimming from half an ocean away
