Earlier today, as I lay on my back in the thinly-curtained physical therapy room, neck in a heat wrap, wondering what the inventor of drop ceilings had against the world, three people--a PT patient, a physical therapist, and the PT patient's companion--conversed on the other side of the curtain. Apparently the PT patient's doctor wants him to switch PT clinics so that she might better keep an eye on his therapy. I followed the exchanges just fine until they started speaking in some mysterious boat code.
PT patient: "I don't want to switch boats in the middle of the river, you know?"
physical therapist: "Yeah. That ocean thing doesn't work."
PT patient's companion: "Yeah, 'cause sometimes then you're left without a proverbial paddle or a boat."
