Most of Facebook's adult supervision gave the Facebook Prom a skip, we hear. But not recently hired Google execs Elliot Schrage, now Facebook's top flack, and Sheryl Sandberg, the formidable new COO who's revising Facebook's internal social graph day by day. We heard Schrage and Sandberg were tight at Google, but close enough for this "me-and-my-bitches" pose captured at the Facebook Prom event held two weeks ago? (Camille Hart, Sandberg's assistant, is on the left; she also followed Sandberg to Facebook.) Suggest a caption in the comments, and the best will become the new headline. Yesterday's winner: abmw, for "They never have enough restrooms in these Apple Stores."
