While working at Superstore USA in "Hell Comes to Quahog", one of Meg Griffin’s duties is to give him a Baby Ruth candy bar. He then states that he is “already in a committed relationship”, presumably with Chunk. After Stewie shave his head and Lois convinces him he looks like a celebrity in "Chap Stewie", Peter signs an autograph for a fan whom he thinks believes him to be Bruce Willis, but who actually thinks he is Sloth.
