Later, she decides to teach an art class at the prison and eventually helps Jack get parole. With Jack released in her custody, Marge sets him up with a job painting a "Puma Pride" mural at Springfield Elementary School. Jack angers Principal Skinner by painting a shocking Heavy Metal-style mural which he is forced to paint over. When the new mural mysteriously catches on fire, all fingers point to the newly-released prisoner. Marge and Jack have a heart-to-heart and she tries, one last time, to help him.
