Season 9: Episode 5 - Knight Vision

Knight Vision: Ted has promised Barney that he will remain loyal to Barney. Barney warns him, like the knight at the end of Indiana Jones And The Last Crusade, that he must choose his hook-up for the wedding wisely, otherwise he will choose poorly. Ted ends up choosing a hot mess. Robin and Barney meet with a minister and, feeling judged on their slutty past, steal Lily and Marshall’s meeting story.
