I'm pointing out this story about a man selling illegal orchids on E-bay just to highlight this paragraph:

"When a man falls in love with orchids, he'll do anything to possess the one he wants," Norman McDonald wrote in his 1939 book The Orchid Hunters. "It's like chasing a green-eyed woman or taking cocaine, it's a sort of madness."

"It's like chasing a green-eyed woman." Isn't that a wonderful phrase?
