Sardonicus

Sardonicus, also known as Terrance is a prisoner in Waterville Prison.

History
When teaching an art class, Marge tells him to use more brushing instead of stabbing actions. He was painting a picture of someone stabbing a judge.

He was moved to Springfield Penitentiary as he is seen when Artie Ziff is extinguishing the prisoners' cigerettes.
