s03e10 The Luck Of The Fryrish

After a period of very bad luck, Fry thinks he must be the most unlucky man on Earth. This sets him remembering about the time when he was younger and he found a 7 leaf clover. The clover made young Philip very lucky, and Fry decides to go to the ruins of Old New York to find it. Once there, Fry finds a statue of "Philip Fry: The First Martian" - but it looks like his brother Yancy, who always copied Philip! Fry thinks his brother stole his name and the clover, and he, Leela and Bender go to Yancy's grave to get the clover. At the grave, they start digging, and Fry reads the text on the stone which explains what happened. Yancy did find the clover, but gave it to his new born son Philip (named after his uncle) who was the first man on Mars. Fry puts the clover back as a mark of respect.
