Matt Damon claims he used the air in Tom Brady's footballs to clear his bronchitis-suffering nephew's lungs. Just one of the stories told by celebrities-posing-as-Massachusetts-residents on 'Jimmy Kimmel Live.' Funny, funny stuff!

Along with Damon, stars like Ben Affleck, John Krasinski, Chris Evans, Aerosmith's Steven Tyler, Eli Roth, Dicky Barrett, and Bill Simmons claim 'I am the locker room guy.' I'm not sure which is funnier, the stories or the accents! Of course, Damon and Affleck do it with ease as they're both Massachusetts natives!

Be sure to watch the video to the end and catch an amazing burn on Damon from Jimmy Kimmel. Awesome!
