Ha, well the funny thing about anime is, if you watch enough of it, you'll pick up some Japanese. However, it will be anime Japanese, and to native speakers, it will sound real otoku. I heard of a guy that kept saying "atashi" when he was referring to himself, but that is because he was always hearing girls say it. English doesn't have a male/female form for "I", he just thought that's how you say it. Needless to say, he got a few funny looks.
I love watching anime where they have to American otoku come to Japan, and they don't know better, e.g. Patricia Martin from らき☆すた.
