One of the 2E Volo's guides talks about a Dalelands delicacy, wyvern's tail. Yes, it's exactly what it sounds like -- the tail of a wyvern, cooked. However, because hunting wyverns is not exactly for the faint of heart, there's a dish called 'jack wyvern's tail' which is basically an imitation, using chopped pork and a couple other ingredients.
Someone once pointed out that if a set of dragonhide armor was of relatively recent vintage, it would be a valid target for a resurrection spell (since those spells typically only require a part of the body, not the whole thing). Take care when skinning that red dragon, folks -- it'd be a hell of a thing to have your nemesis be returned from the grave AND lose your custom suit of armor.
