Ben (as Stinkfly) is lecturing the other animals about teamwork and mentions "Who is more foolish, the fool or the one that follows?". This is an almost direct quote from Obi-Wan Kenobi in Star Wars Episode IV - A New Hope when, as the Imperial Stormtroopers are exiting the Millennial Falcon after scanning the ship, Obi-Wan tells Han Solo "Who is the more foolish? The fool or the the fool that follows him?".
