Keller played Marco Polo with Stewie Griffin in "Peter's Got Woods". Stewie found no enjoyment as he kept on saying Marco but Helen would never say Polo, since she could not hear him. She also did not move, as she could not see anything. A performance of The Miracle Worker is performed in binary code in "Brian Wallows and Peter's Swallows". In a DVD-exclusive argument between Stewie and Mort Goldman in "Road to Germany", Stewie says that even Keller would notice that Goldman is Jewish. Brian found the joke amusing.
