All joking aside, we know from the book what an incredible horn dog Bret is. He's saying shit about Melina that no rational person, especially one who has seen and taken part in so many incredible matches, could possibly believe. It's clear that Bret has decided to compromise all his integrity, risk further damaging his brain, and perhaps harm his legacy with the wrestling fans, all in an epic quest to hit that. And I find that admirable.
