Well, my brother really really loved Full Metal Alchemists. He watched both Brotherhood and the first series on his own after we watched the first few episodes together.

He's also watched an episode of Chobits(the first one) with me and was laughing throughout it...

Also, we watched the first episode of Pumpkin Scissors together and we both agreed we needed to watch more of it.

But I really want to make it so he doesn't associate anime with breasts and panty shots.
