Although live theater possesses a spirit of unpredictability and spontaneity, releasing a siberian tiger on stage to test the actors' dedication to their characters is generally frowned upon. Play the role of a dutiful audience member with today's Groupon: for $22, you get one ticket to see Girls Night: The Musical at The Long Center, presented by Entertainment Events (a $44.50 value). Choose between the following dates:

• October 7 at 8 p.m.
• October 8 at 8 p.m.

Girls Night: The Musical plots five friends at the center of The Long Center's stage as they ponder their past, celebrate their present, and silently think about robot designs for the future during one comedic night of karaoke. Actresses belt out renditions of such female classics as "It's Raining Men," "I Will Survive," and “Lady Marmalade” amid vibrant set pieces, and Dell Hall's excellent acoustics ensure that all 2,400 guests can catch even the faintest stage whispers. From the velvet seats, audience members bask in the waves of heartfelt tunes, watching as their theatergoing compatriots abandon upscale etiquette and boogey away in the aisles. Purchase up to eight Groupons and bring along seven besties or the whole women's freeze-tag team.
