Well that didn't turn out as planned

OK so I was watching anime on my computer right? And I'm watching it in Japanese with English subtitles because the English dub of this particular anime SUCKS.  God forbid that the characters have any personal growth throughout the show, good voice actors, and that the show have its main romance actually in the English dub . . . I'm off topic.  Anyway I click on the next episode and this horrible sound assaults my ears.  It was the opening to the English Dub and I'm thinking WTF.  . . So I refresh the page and it does it again. I click on the tab that says English Sub and it does it again.  I finally get the idea to click on the English Dub tab and lo and behold the Japanese opening pops up immediately.  Apparently the site I was watching screwed up majorly and switch the dub and sub of this episode.  It freaked me the hell out for a second there though.
