Got a case of Mary Poppins malaise? This $5 Groupon is a spoonful of sugar for the medicine: tickets to Girls vs. Boys ($10 value). The play, a musical by the creative team behind The House Theatre of Chicago's sold-out show The Sparrow, is an extremely loud, fast-paced show about a brother and sister who find themselves thrust into a perilous, modern-day Lord of the Flies. High-stakes relationships turn into all-out war of the sexes. The director says it's like a rock concert, so the best way to experience the sound and fury is with a spot in the pit. This Groupon gets you in standing room and on the ground floor of the action (guaranteed swears, awesome music, violent themes, and partial nudity).
