Bizarro Episode: In one of the crossover comic books, Howard the Duck tries to register. Not because he supports the law, but simply because he's too poor and cowardly to be running away from Iron Man and simply wants to avoid trouble. But he got into the wrong waiting line and wound up renewing his driver's license instead. When he found the actual place for registering, he was rejected—SHIELD is so tired of receiving reports about "the duck man from Cleveland" (the duck man driving a taxi, the duck man insulting hot dog stands, the duck man painting graffiti in bus stops, etc), that they made it an official policy that he does not exist, and all the reports are dismissed. He yelled that they can not turn him into an Un-Person just like that.
Agent: Of course you are an unperson. You're a duck.
