Mickey Mouse's birthday is celebrated today because on this date 83 years ago, he debuted in the animated cartoon Steamboat Willie. But actually, this is more like Mickey's Gotcha Day. Cause he first was seen in a test screening of Plane Crazy May 15, 1928 but the audience didn't like him. Then he was in another short - The Gallopin Gaucho, but none of the distributors wanted him. So Mickey and I have that in common. We were both rejected twice until we found our forever home. Happy Gotcha Day Mickey!
