John Krasinski's Awkward Introduction to Matt Damon

On Tuesday's Conan, John Krasinski shared his strange first encounter with Matt Damon. Krasinski, who grew up near Boston, was a big fan of Damon's. So Emily Blunt, Krasinski's wife, was filming The Adjustment Bureau with Matt Damon and invited Krasinski to the set. They were filming on the top of the 30 Rock building. Krasinski showed up and was whisked to a tent with a monitor that showed Emily Blunt and Matt Damon kissing on-camera. After the take, Matt Damon came to meet Krasinski and said, "Hey, nice to meet you. I was just totally tonguing your girl." John Krasinski was horrified at the joke. He told Conan O'Brien, "He started to melt. And he went, 'I'm so sorry, that wasn't funny at all. I'm so sorry.' To this day he can't get over the fact that that's first thing he said to me."
