Elves drinking with Orcs? Unusual, but it's in the Elves of Alfheim Gazetteer. The PCs were tailing an Orc troublemaker, and getting the rehabilitated Orcs in town to speak with them involved a drinking contest. Two of the Elves won their contests, but the third passed out after his first drink! From now on, he will always be known as a lightweight, no matter what he does.
