Heard on Radio From Hell, April 8th, 7am hour:
Gina, "It's like a future McDonald's. Doesn't it look like it came from the future?"
Bill, "Or... Or the hip past. You know what I mean, it's kind of retro-y... Back in the 60s, this is what people said the future would look like."
Kerry, "That, uh, future-slash-retro, I love that stuff."
Bill, "Pop-art."
Gina, "Futro."
Kerry, "Futro!"
