How do I get rid of the Pinterest button on my blog?

I don’t remember even adding a Pinterest button to my blog, but I’ve been months building the dang thing, so I guess I don’t remember. Or maybe the guy who runs our local WP Meetup did it for me.

In any case, this button used to be red, now for some reason it is gray. Not only that, but I’m not ready to be linked to Pinterest yet anyway, as I’m still trying to figure Pinterest out. So I thought for now, I’d just get rid of that button. I honestly have no idea how I managed to to get it on my site in the first place, as I don’t have a plugin for it.

I just want it gone!
