My friends and these two guys tease me about Detective Conan.
One friend in particular, my current best friend, was always arguing with me about which one was better, One Piece or Detective Conan. I'm pretty sure most of you can guess which side I was on.
So one day at lunch, I said, "DC is so much better than OP, and you can't retaliate because I've tried OP and you haven't tried DC."
So of course, she decided to read DC just to prove me wrong...and by the end of the day she was hooked.
She still calls me a DC otaku though. I'm proud of it.
