Weirded Out

This was the weirdest thing that has ever happened to me in my life. I'm pretty dang sure that it was just a prank pulled by somebody, but I wouldn't be surprised if it were the real guy.
I was checking my Facebook page this morning before school and I had a few notifications, so i was checking those and there was this one that said "Grace, Barak Obama confirmed you as a cousin on 'We're Related': see how you are related" So, already I'm thinking "What the heck?" so I click on it, and it brings up the page that has the names of a bunch of different people in a pedigree chart that says that my great-grandparents' names are Charles James Smith and Pearl Marie Petersen. Don't ask me how ANYONE could come up with such a thing, because I know the names of my great-grandparents and Charles and Pearl are NOT them. So, according to some nut-job out there in society, I'm apparently related to Barak Obama. That makes me laugh.
