Principal Seymour Skinner
Voiced by: Harry Shearer
With a much-disputed Vietnam War background, Skinner is a strict disciplinarian and constantly-mocked authority figure. He lives in constant fear of State Superindentent Chalmers, as well as school rebel Bart, while also cowering under his mother Agnes' all-dominating shawl.
Edna Krabappel
Voiced by: Marcia Wallace
A 4th grade teacher, Bart oscillates from being the bane of her existence and her only confidant. A woman with a ravenous, mostly-unfulfilled appetite for the opposite sex, Edna is a jaded teacher frustrated with an on-again, off-again relationship with Skinner.
