Dude, don't be a dick. Just because the thread's flooded with pics from a certain anime doesn't mean everyone knows wtf it is. In any case, I think it's funny that you bitch those guys out about not knowing whatever, but that one dude gets away with asking about a picture that's from an opening of Blood+. And then that other guy makes a reference to a song from a completely different OP. And no, I'm not either of the assholes you bitched out, I'm just some guy who didn't know what they were either.
tl;dr: go fuck yourself
