Redditor Sandbrink lives next door to a little boy named Joey who recently turned 10 years old. Also living in Joey's neighborhood is Nori Aoki, right fielder for the Kansas City Royals, who are currently playing in the World Series.

In any case, Joey woke up to this amazing surprise in his mailbox on the morning of his tenth birthday: exactly the kind of gift that little boys dream about.
