Finally fed up with his horrible luck, Fry searches for his long-lost seven-leaf clover and discovers his copycat older brother stole his name and became an Earthican hero. Only at the end do we discover Fry's petty resentment of his brother to have been misdirected, and said hero was actually Yancy's son named after Fry. 

The emotional gutpunch took us completely by surprise, and let Philip quietly shine as he relinquishes the clover to his nephew's tomb in tears. We then punched our own siblings for not being as close.
