Conflicting issues involve the fact that despite the map displayed in this episode, Washington D.C. is referred to as such, rather than Washington A.C. and "New New Jersey" is often referred to as just "New Jersey". Additionally, in the episode "The 30% Iron Chef", Bender references Eugene, "Oregon", differing from "XORegon". Presumably these state parodies were only thought up for this episode as they are not used at any other point in the series.
When Bender first talks to Beck in the hospital, Bender is never introduced, although Beck says, "Bender, I want you to be my new washboard player." It is implied that Beck overheard the talk in the room, although it is not clear.
