The topic was body modification, and he explained what was taboo to him and other bodybuilders, which was surgical modification of bodyparts, like implants. He was very clear and crisp and didn't come off as a musclehead, and he was being interviewed backstage, after a call out.
They had some idiot who was a male physique model who got pec implant, and then he wants to go bigger (sounds very much like women who get breast implants), and then they had another dude who was getting glute implants (too scared to squat?)
There were others, but it was a good episode and Vince repped bodybuilding well.
