One of the first things you see after stepping over the Murder House threshold and into season one, is mad surgeon Dr. Charles Montgomery. In between cutting away at something gruesome on the table, he lashes out at you with his surgical tools. If pressed, I'd give his bedside manner a solid 3/10.
(note: his terrifying son Thaddeus, a.k.a. Infantata, also jumps out at one point, and it shaved approximately 63 years off my young life)
