The Actor's Nightmare & Sister Mary Ignatius 
Explains It All For You by Christopher Durang

The Actor’s Nightmare is a hilarious satire detailing the plight of a stranger who is suddenly pushed on stage to replace an ailing actor. In Sister Mary Ignatius Explains It All For You, the titular Sister, a teaching nun who is much concerned with sin in all of its various forms, delivers a cautionary lecture to her charges. But when several of her former students turn up the picture darkens, along with Sister Mary’s indignation.
