Bug, Redtwist Theatre, extended through Aug. 7. It’s a scary world we live in, and never more so than in this tabloid-fueled early tale by Tracy Letts about humble lovers driven to suicide by their own terrors. Redtwist Theatre gives us a—well, bug’s eye view of every last detail. MSB

El Stories: Brown Line, Waltzing Mechanics at the Greenhouse, through Aug. 13. Even a CTA line with no owl service is filled with adventure in this invigorating late-nite revue ending in plenty of time for Ravenswood dwellers to ride the real thing home.

The Homosexuals, About Face Theatre at the Biograph, extended through Aug. 14. A decade in the life of a once-naive young gay man, told via two-person flashbacks through friends and lovers. Philip Dawkins’s serio-comic world premiere is smart writing, well-acted. JA

Sky’s the Limit (Weather Permitting), Second City e.t.c., in an open run. American aspirationalism gets spoofed with sarcastic pessimism in this great new comedy revue that unabashedly leans left with its wit and humor. SCM
