We are all at our most vulnerable following invasive oral surgery—still zonked out on the pain meds and primed for drugged-out YouTube stardom.

The Phillips brothers of Leesburg, Virginia took full advantage of their sister Millicent’s wisdom teeth removal surgery to convince her that they were in the middle of a zombie outbreak.
