God Louie : Season 1 Episode 11

When a nun at his Catholic school feels a young Louie and his friend aren't sufficiently penitent over Christ's suffering on the cross, a visiting doctor is brought in to give a graphic, medically specific description of the event, which haunts and frightens Louie. But Louie's mother turns up in a new incarnation as a wise and loving parent who tells Louie that relying on dogma isn't the best way to be a good person.
