Um, it tastes like dirt

I am a philistine. For a long time I wondered vaguely what all the fuss was about black truffles. As far as I was concerned truffle = chocolate. They turned up on various cooking shows, and the Iron Chefs seemed to toss them about with gay (yet deadly serious) abandon, like excited ninjas. Last week I saw them used not only twice, but in the kind of simple recipes designed to show off their unique flavour.

Have you had a truffle experience? Should I be shunned from society for failing to immediately appreciate a delicacy? I've always suspected that "delicacy" was the culinary technical term for "practical joke". Must I now abandon my middle class pretentions?
