Tina Brock’s Idiopathic Ridiculopathy Consortium shows again and again that absurdist theater is out there for anyone willing to let go of rigid plot expectations and plunge into an adventure. Take this seldom-performed Charles L. Mee comedy, about hapless characters who “escape the animal way of life” in an endless amusement park that they seem unable to leave. Brock and inventive designers Anna Kiraly (scenery), Josh Schulman (lights) and Erica Hoelscher (costumes) make low-budget magic in the cozy 50-seat Walnut Street Theatre Studio 5, creating a collage of carnival fun spliced with everyday befuddlement and anxiety. From boat tours going nowhere and a fruitcake catapult to a family’s tenuous connection after losing a child and a blossoming romance, Paradise Park explores our desire to escape our lives with wit, philosophical insight and a great deal of silliness. Now in its eighth season, IRC continues to prove, as one Paradise Park visitor quips, that “everything isn’t not possible.”

Through March 3, $20-$25, Walnut Street Theatre Studio 5, 825 Walnut St., 215-285-0472, idiopathicridiculopathyconsortium.org.
