Here are some Eric Dane photos for the gals. If you will recall, Eric became known all over the world when he guested as Dr. Mark Sloan in the eighteenth episode (2005) of the second season of the ABC medical drama Grey’s Anatomy. The positive audience reaction to the character led to Dane’s becoming a regular in the show’s third season. His first appearance in the season, in which he walked out of the bathroom soaking wet and wearing only a strategically placed towel, was labeled a “watercooler moment.”
