This is a reference to the 1989 adventure film, Indiana Jones and The Last Crusade. The film stars actor, Harrison Ford, as the adventurer, Indiana Jones, who is searching for the fabled Holy Grail. Towards the end, Jones finds a knight who is guarding the Holy Grail although he doesn’t reveal which one of the goblets is the actual Holy Grail. Jones has to choose between several flashy and not so flashy goblets.
Action Bronson isn’t looking for the Holy Grail, instead he’s flexing his wealth by buying expensive cups like Jones.
