 In the episode "A Leela of Their Own", Leela takes advice on  Blurnsball from a descendant of Hank Aaron (qv). He wears an  Atlanta uniform, but instead of there being a tomahawk on it (like  there would for an Braves jersey), it has a trident. This is a  reference to the episode "The Deep South", where it is revealed that  the city of Atlanta was moved to the middle of the ocean, where it  sank to the bottom of the sea.
