Call it useless facts, trivia, things you didn't know (or didn't want to know), whatever you want, but there are some that leave you aghast or surprised or wondering what the hell were they thinking?

I enjoy learning these facts, because it makes me feel smarter, and I sure could use more smarts!

Anyway, ThumbPress.com has listed several facts that are, how should I put this...interesting?
