What is the most disrespectful thing a boxer said to or about another boxer?

I remember Sonny Liston saying that, the then Cius Clay would be some one's bi-t-ch in prison or words to that effect. We have Mike Tyson eating Lennox Lewis's children. How about Benard Hopkin's saying no white boy could beat him or the mean horrible things Ali said about Joe Frazier. I am sure I missed a lot. Please chime in.
