German comedian's Joko Winterscheidt and Klaas Heufer-Umlauf host a TV show where they pull pranks. They set up an agency and told award show producers they could get Ryan Gosling to come to their event if he knew he was winning an award.
They took the bait! They have a friend who is a cook in Munich, named Ludwig Lehner who looks a little like Ryan show up. The host then said "one of the hottest stars in Hollywood is with us! The one and only Ryan Gosling"! Their friend 'I dedicate this award to Joko and Klass, thank you very much. There is a saying in Hamburg, which is, 'bye, bye!
Here is the video of how they pulled it off and the results.
