I have a question, what were said on the radio

The radio in the movie emits a string of non-sequitirs. I don't remember exactly what they are, but I remember one line: "A single glass of water lights the entire world." I haven't seen in a long while, but I just got it tonight, so I'll have a look and give you a more precise rendering.

Young man, I think you're onto something... now climb off and let me have a turn.

I would not call them non sequiturs, but nice examples of surrealist juxtapositioning. Many Surrealists were militant about the superiority of their aesthetic, and I think Cocteau is alluding to this when Orpheus feels he has discovered a great new source of inspiration
