Faith Salie asked if "Batman & Robin" movie is the one which Batman had nipples. At which, Mark Bittman responded with, "that answers the first question" and Peter stating, facetiously, that he will never invite Faith Salie back on to the show. Mark was in fact right that it was the correct answer to the first question and was the only question Mark answered correctly.
At the beginning of the Lightning Fill-in-the-Blank round, when Carl provided the panelist's scores and standings in which Luke was third with 2 points, Peter said, "Luke you're definitely going to go third". Luke actually went first. Funnily enough, Luke ended up coming in third at the end of the round.
