Where the Sun Don't Shine

So despite my vow to start fixing my hair again, here I sit with a bun today (albeit a lower than usual bun to mix things up a bit). It was at one point today secured with two bobby pins. My fine, thick hair is none-too-friendly with the bobbies, and spits them out on the reg. In fact, one was just spit out and fell down the back of my pants. But herein lies the tricky part, I cannot find it in said pants. Now I'm terrified that instead of a bobby pin in my bun, I have a bobby pin in my bum.
