This is a simple concept wrestlers who aren't active should have already jumped all over by now, and The Rock executes it well. All he does is watch back a match, in this case his debut bout for WWE at Survivor Series back in 1996, and react to it. Here, he runs himself down for that god awful haircut he was rocking at the time but also gives some great insight into what he was thinking.
Like how he screwed up his entrance by not playing to the hard camera, or how the fans chanting his name when he was the last member of his team left changed his life/career, or how he told Crush "thank you" while pinning him to show his gratitude for the veteran putting him over.
It's also just plain fun, considering it's The Rock and he knows how to make it entertaining.
