A pick-up line isn't always intentional.
Every now and then, when meeting a gentleman, he will inadvertently say something in the course of conversation that, unbeknownst to him, is the most romantic, heart-stopping phrase a girl has ever heard.
Case in point: on Saturday night, in a cosy alehouse in Surry Hills, I was engaged in getting-to-know you conversation with a tall, handsome gentleman. I asked him what he did for a living, and he said, oblivious to the effect on my heart and loins:
"I make beer".
