Found a squick

I've been watching the TV series Bones on Netflix. Formulaic mysteries with humor; it's awesome. Anyway, since it's all about murders there have been bones and bugs and tissue pieces and blood, and I've made it through all that with no problem. But this episode (s9 e22) they've been talking about fingernail beds and my body has gone NOPE NOPE NOPE NOPE NOPE. Interesting that this would be the one thing that would do me in.
