When Vineyarders tuned in to FOX yesterday afternoon, they found the familiar, reassuring visage of Dr. Mehmet Oz. Next to him was an even more familiar face, that of Islander Marcy Holmes.

“It was a surprise. I haven’t been groomed for this,” Ms. Holmes said Thursday. “I don’t have the stage experience that Gerry has,” a lighthearted reference to her Vineyard Medical Services colleague and man of the stage Dr. Gerry Yukevich.
