Jackson Hughes got his first Lego set, the Adventurer’s Scorpion Tracker, as a gift from his best friend when he was a child. But no good deed goes unpunished, especially in the reckless days of childhood, and a few years later, when he was roughhousing at the best friend’s home, the Lego version of a starship flown by Star Wars character Jango Fett came crashing off the top of a bookshelf.
