 At the end of the second episode on Region 1 DVD #1 there is a joke  added by the ADV production team, which requires that the viewer  watch both the original Japanese and the English dub versions simply  to notice it. In the final scene of Episode 2, Excel is being  interrogated by a band of soldiers. In the dub version, one asks her  "What is your purpose?", to which she inexplicably replies "A big  fish?" In the original Japanese, her answer is a simple "I dont  know"
