In his "uncensored" interview with NBA 2K, Michael Jordan told a story of how a young O.J. Mayo was talking trash to him at a camp. The two went back and forth, with Jordan jawing at him, and eventually Mike took it serious and shut Mayo down while scoring easy buckets on him.
O.J. Mayo still remembers the scene and describes it, saying that MJ told him, "you may be the best high school player in the world, but I'm the greatest...ever, and don't you ever disrespect that."
