This video from PBC Boxing is a must see. When you watch it notice the look on both fighters faces as you can see Manny slowly but surely look like he just wants to smash Keith.
As the interview goes on Keith gets more nervous.
The classic moment was when Keith was egging Manny on about his lack of power and he kept asking Manny "how many knock outs have you had Manny?" Then Manny softly responded 40 (he really has 39). Manny has more KOs than Keith has fights (30 fights 22 by KO).
