Late Nite Catechism just might be the sell-out comedy of the summer. The one-woman show features Sister (no given name needed), an Everyman nun. Notorious for castigating misbehaving audience members with everything from a ruler to a good long sit in the corner, Sister has become a celebrity of interactive theater, where every show is different. There are, of course, some standard jokes about all things Catholic, but most of the fun comes from the interchange between Sister and her audience. So, go, and be good! Because if youย’re very, very nice, you just might earn yourself a lovely glow-in-the-dark rosary or some other blessed token of the good sisterย’s approval.

Thursdays, Fridays, 7:30 p.m.; Saturdays, 8 p.m.; Sundays, 3 p.m. Starts: July 13. Continues through Sept. 30, 2007
