Well here I go dating myself, but there is a miner's quest is called "Smelt On, Smelt Off", which is a reference to The Karate Kid and "Wax on, Wax off". Over three quests you have to bring the guy a whopping 160 metal bars (40 iron and 120 Mithril) and some odds and ends. It's a long, mundane task you might not see the purpose of, but it improves your skill greatly. :)
When you're done with him, he sends you to see "His Finest Pupil" Who tells you "Around these parts I am known as the Mithril Kid". His name is Trenton, probably because the Karate Kid was displaced from Jersey.
He also tells you "At last year's All-Valley Blacksmithing Championship, all those who watched saw my leg get swept from under me by a cowardly dog from the Venture Co. Foundry. What they didn't know, however, was the reason I was able to continue and ultimately win the tournament: That's right, ornate mithril boots!" Which is pretty much what happened in the movie. (Not the Mithril Boots, but his training)
