Mark Wahlberg gave an entertaining interview here. He is probably an egomaniac in real life, but he almost always comes off as personable during these kinds of interviews, and this was no exception. He did not just plug that annoying The Other Guys movie, he also talked about sports, especially boxing. That is better than most people will do.
David Otunga was not as entertaining as the previous WWE wrestlers who have appeared on the show. Otunga's song was absolutely awful, he was just talking. You would think that someone married to Jennifer Hudson would be a better singer than this.
