Uncle Hayseed is a character in The Sims Bustin' Out. He is the player's uncle and lets the player's character move into his barn on Hayseed Farm, gives the player some items and a job mowing his lawn. He is kidnapped by Giuseppi Mezzoalto and is threatened to be killed with a guillotine. Sometimes in The Urbz, he will call the player's Sim and ask them when they will visit because the chickens miss them.
- A reference is made to Hayseed in The Urbz: Sims is the City, if the player catches a Chicken on the Bayou, its item description will read: "A chicken from Uncle Hayseed's farm".
