Arcadia, Court Theatre, through June 10. Sex, literature and math dazzlingly collide in Tom Stoppard's funny and brainy tale of poetry, time travel and the powerful attraction Newton overlooked. Arcadia has the power to make you weep with joy and heartache. CS
The Frogs, Pegasus Players, Truman College, through June 3. Aristophanes is updated by Bert Shevelove, Nathan Lane and Stephen Sondheim and performed in a swimming pool. The aquatic chorus in wetsuits never misses a note. Ribbit! Comedy tonight! MSB
The Intelligent Design of Jenny Chow, Chicago Center for the Performing Arts, through June 3. It's a transfer of Collaboraction's serio-comedy about the Internet, AI and a trash-talking teen genius seeking her roots. Astonishing performance by Jennifer Shin. JA
Pulp, About Face at Victory Gardens Greenhouse, through June 3. Patricia Kane's affectionate satire of lurid 1950s lesbian fiction is just as delightful the second time around. The cast sparkles in this winning revival, sharply directed by Jessica Thebus. JA
