What is the moon?

The whitish zigzags are made by night insects attracted by the neon lights.

"BOYLE:  I seen things, I seen things, Joxer, that no mortal man should speak about that knows his catechism. Ofen, and ofen, when I was fixed to the wheel with a marlin-spike, an' the wins blowin' fierce an' the waves lashin' and lashin' till you'd think every minute was goin' to be your last, an' it blowed and blowed - blew is the right word, Joxer, but blowed is the word the sailors use....

JOXER: Aw it's a darlin' word, a daarlin' word. 

BOYLE: An' as it blowed an' blowed,  I ofen looked up at the sky an' assed meself the question - what is the stars, what is the stars? 

JOXER: Ah, that's the question, that's the question - what is the stars? 

BOYLE: An' then, I'd have another look, an' I'd ass meself - what is the moon?

JOXER: Ah, that's the question - what is the moon, what is the moon?"
