It looks like Ellen really made a boob of herself when she made a joke (near the end of this video, ~2:45) about a real estate broker with the name of Titi Pierce. That name is actually pronounced 'Tee-Tee' for the record and she wants to make sure everyone knows it. That's why Titi Pierce is suing Ellen for the humiliation that joked caused. Her claim is that she has experienced pain and suffering due to the crude jokes at the expense of her name that, Pierce says, have never occurred to anyone before Ellen made that joke on her show.
