S3·E11 To Spank, with Love

After being taunted and pantsed by one of her students, Peggy loses it and spanks him. She is immediately fired, but Cotton and his old buddies start a campaign to get "Paddlin' Peggy" reinstated. Once she is back teaching, Peggy uses her reputation for violence to scare her students, and takes things too far, in true Peggy fashion.
