Lora Adams and Kimberly Furness in Swimming in the ShallowsTruth be told, playwright Adam Bock's Swimming in the Shallows - currently being produced by New Ground Theatre - is a bit of a mess. If, however, a show is fortunate enough to feature Pat Flaherty and Susan Perrin-Sallak as a bickering married couple, Eddie Staver III performing an underwater pas de deux in scuba gear, and a tuxedo-clad shark dancing the Macarena, it doesn't much matter if the script falls apart.
