Ryan Gosling dressed up in a vest and tie for his appearance on Jimmy Kimmel Live! in NYC last night. He's gearing up for the release of his latest project, Gangster Squad, which hits the big screen tomorrow. During his stop by the show, Ryan had a hilarious chat with Jimmy about Girl Scout cookies, during which he confessed to being a "creepy cookie guy." He also did a funny "Knife Guys" skit with Will Ferrell. Ryan's Kimmel appearance comes after a busy promotional week for Ryan and his costar Emma Stone. On Monday, Ryan and Emma hit the red carpet for Gangster Squad's LA premiere, and this morning, Emma joined Oscar host Seth MacFarlane to announce this year's Academy Award nominees.
