Scary Miss Mary is a notable listener who rose to prominence within the Schlock Treatment community shortly after discovering the show. Starting from the first episode, she binge-listened to well over 150 Schlock Treatment episodes in just a few weeks, updating the hosts on her progress through the comments section. She quickly became a fan of Marc McDonald, despite the fact that she began listening to the show months after his departure.

Since bursting onto the scene, she has remained a regular listener and continues to comment regularly on the Schlock Treatment website.
