Worried that this season’s set of “True Detective” crime solvers can’t live up to the work of Matthew McConaughey and Woody Harrelson? Jimmy Fallon offered them the platform of “The Tonight Show” to show off some of their detecting skills last night. Colin Farrell and Vince Vaughn both played a quick round of “True Confessions” with the host. Each participant had one true story and one false story to share, while the other two had a minute to ask a series of probing questions to determine whether or not they were lying. We don’t want to reveal too much here, but we will say we were pleasantly surprised to learn some really bizarre things about these people, and to see Vince Vaughn show off some singing skills. Think you can predict what’s true and what isn’t? Watch below, and test your own detective skills.
