When Ke Huy Quan's character, OB, reveals his model he says, "Forgive the shoddy and slapdash work. It's not to scale, I only got one coat of paint on there..." This is a clear nod to Christopher Lloyd's character Dr Emmett "Doc" Brown in Back to the Future (1985) when he, too, reveals a model stating, "Please excuse the crudity of this model, I didn't have time to build it to scale or to paint it."
