delete an "interest" on facebook?

can you delete an interest on facebook that's an VIDEO? I also have an interest I want to delete on facebook in the interest section that's a "website."

when you click on the interest which is either a VIDEO or a WEBSITE it takes you THERE, so there is no delete found on either. I can't even find a delet on facebook for it because it keeps taking me to the youtube video or website when it's clicked. in fact I have three I can't get ride of, and the third is a CAUSE, which when you click it you go "right to the cause" and the "like" hasn't even been clicked by you, so YOU CAN'T UNLIKE IT.

any information on how to delete videos, causes, and websites you put in the interest section? remember whenever you click either one it takes you OFF of facebook, and to the actual video, or website, or cause LOCATION.

any clues?????

thanks
