To understand the punch line, you have to know that the Blade is the Washington, D.C. area gay newspaper; it has traditionally included copious advertisements for "adult services". Many years ago a friend of mine here in the Washington, D.C. area grew and flowered this plant. We all regarded it as quite an event. The invitations went out for everyone to come over and see it. The night arrived, and we all stood around admiring this marvel. Our host, beaming with pride, recounted the story (which everyone present nevertheless already knew by heart) of its discovery and of Darwin's famous prediction. After telling the story, our host paused for a moment, and then commented : "I don't know where in the Washington, D.C. area we could find a moth with a twelve inch proboscis". At that point, one of the group, who had been utterly quiet all evening, without missing a beat blurted out "Put an ad in the Blade".
