If you're in the D.C. area, I heartily recommend that you go see Patience, by Gilbert & Sullivan, put on by Georgetown Law School's Gilbert & Sullivan Society ("America's only theater group with its own law school").
It starts at 8 p.m. tomorrow night (Wednesday, April 11) and runs through Saturday, April 14. Georgetown Law School is at 600 New Jersey Ave. NW, between the Union Station and Judiciary Square metro stops.
This is not as well known as some of their other shows, but it's a little gem of a play. I myself was in the Georgetown G&S Society's production of Patience back in March 1994. Plus, if you show up tomorrow -- opening night -- you may see a certain conspirator in a brief walk-on role.
