Remember the creepy necklace made of human teeth "A" sent the Liars in Pretty Little Liars Season 3, Episode 2: “Blood Is the New Black”? Who are we kidding — that's one image that's impossible to forget!

As we've previously reported, the prop was the real deal: those chompers were actually human! (Though we assume they weren't stolen off of a corpse...). And it turns out that's not the only fun fact about that necklace.

Recently, Brendan Robinson (Lucas Gottesman) tweeted this pic, along with this factoid: "Guess who made the creepy tooth necklace for #PLL? MY DENTIST!! And guess what, they were REAL HUMAN TEETH! Creepy!"

It looks like Brendan's dentist keeps a montage of his/her (it looks like her based on one of the photos) big TV moment at the office. Cool!

Don’t miss the next new episode of PLL, the Halloween special, on Tuesday, October 23 at 8 p.m. ET/PT on ABC Family.
