Shel Silverstein may have been a well-regarded cartoonist and children's author, but he was a very limited dramatist. Many of the ten one-acts in this "best of" show, put together by Silverstein's friends after his death in 1999, are little more than bloated comedy sketches. The folks at Second City could have made their point and gotten more laughs in half the time it takes Silverstein to lay out the story in "One Tennis Shoe," about a woman who can't help picking through the garbage for knickknacks. Worse still are puerile pieces like "Bus Stop" and "Going Once": on the surface these plays send up sexism, but each invites us to gaze upon a female character's breasts. The spirited, energetic, comedically adept Blindfaith Theatre tries to make this tiresome, dated material seem more entertaining than it is, but to no avail. Through 12/18: Fri-Sat 10:30 PM. Theatre Building Chicago, 1225 W. Belmont, 773-327-5252. $10-$12.
