Seven-leaf clover

The Seven-leaf clover is a good luck charm that was found by Fry and it was used in activities such as basketball and break dancing. When Fry had it Yancy tried to steal it so it was hidden in a Ronco record vault. Shortly before Yancy's wedding after Fry was frozen, he found the clover and when his son Philip J. Fry, II was born, he was given the clover. Philip J. Fry II used it to become very successful in his life such as landing on Mars. He was buried with it and Fry tried to get back the clover because he thought Yancy had it but returned it when he found out it belonged to Fry II. The timeline adjustments in Bender's Big Score likely mean that Yancy merely took the clover while Fry was living at Panucci's. Fry was seen using the clover during this time but obviously still stored it at his parents' house.
