When Adam Scott was in second grade, he invited Mark Hamill to his birthday party, and then told all his friends that Luke Skywalker would probably be there. He wrote a letter to Hamill and gave it to his mom. Needless to say, writing a letter to your mom does not result in a giant movie star showing up to your second grade birthday party. He told this story to Jimmy Kimmel last night on Jimmy Kimmel Live. He also said that years later he thought it would be funny to ask Hamill on Twitter why he never showed up. Hamill wrote back, and we could recreate this whole thing.
