Will Rogers was an American humorist and writer who lived during the 19th and 20th centuries. Rogers was famous for once noting that, "diplomacy is the art of saying 'nice-doggie' until you find a rock." In 2372, Commander William T. Riker repeated this quote to Captain Jean-Luc Picard when he informed the senior staff that he wanted to negotiate with the Changeling infiltrator. Riker admitted that he didn't know if the Enterprise crew were the rock or the dog. (TNG eBook: A Sea of Troubles)
