In Late Nite Catechism, the irrepressible Sister teaches class to a roomful of "students." Throughout the course of the class the benevolent instructor rewards the "students" for correct answers with glow-in-the-dark rosaries and other nifty prizes. Naughty students may well find themselves on stage sitting in a corner reflecting their actions. However, even the most reluctant "students" will be clamoring to get into this Sister's class.
