Or several dozens of Wolves to get a few wolf pelts.. That was the second quest in my short-lived experiment to see if WoW could hold my interest, using a free test account. (Which might have been another example of a self-fulfilling prophecy. I really did hope I would not like WoW. I knew it would become a time sink for me if I would like it.)
Off course, D&D also has these "drops" - All monsters in 3E have a "Treasure" entry that stats stuff like "No", "Standard", "Triple Standard, no Scrolls". Though if you would cut down 12 Kobolds and the DM wouldn't give you 12 kobold tails for it, this either meant
1) Kobolds just don't have tails and someone tricked you into accepting a pointless quest!
2) The DM's need some "reeducation" in form of being pelted with dice.
