In the world of boxing, nicknames are quite common. In many cases, it seems almost to be a requirement to have one. I had a friend who once who tried boxing named Burton Alvero. I gave him his nickname (which he loved). It was Burton "I'll be applying the Hurtin" Alvero. Sadly, he lost both his two amateur fights. All the boxers in this quiz were very famous and almost all of them were champions. Ring the bell! The match has started! This 25 round contest begins now!
