It is revealed Grampa used to be a wrestler under the ring name "Gorgeous Godfrey".
Bart spraying the crowd with perfume is a parody of 1980's WWF wrestler Rick Martel, whose gimmick was that of a conceded arrogant heel who carried a bottle of perfume with him to the ring, in which he would spray on his opponents.
In The Homer They Fall (1996), a deleted scene revealed Grampa was also a boxer at one point, along with other members of his family.
