I assume that you (educated ad culturally aware readers) are familiar with David Byrne's excellent song and video Once In a Lifetime.
This Donald Trump send-up though is funny and topical.

Into the blue again after the money's goneOnce in a lifetime, water flowing underground…"
- same as it ever was.
