Sci Fi Saturday: The Pilgrims

The aliens' religion made no sense
Until Wade Poppy stole the new device
That Doctor Grimes invented (at expense
Beyond belief) that, when activated twice
Sent pulses to observers' brains that made
Beholders see themselves when looking at
A stranger of another species. Wade
Gained entry to their Temple Ararat
(It's not known why they built there). What he saw
Explained it all. Their ancient god, a twin
To Ronald Reagan without e'en one flaw,
Was why they showed such ecstasy when they
Met humans. They had come to earth to pray!
