This week, we all know that they don't know that they know that they know that they know. Ross, with Comrade Rachel's guidance, knows that he can get back his edge by joining UNG for a nude hang...the way God intended. Monica and Chandler know that the girls are trying to be real slick with them. Phoebe and Rachel know that they can use their proximity and sexuality to get an edge on the secret couple. Joey knows that he's got secrets of his own to keep track of. Meanwhile, in various parts of the country that are not Manhattan, April knows she doesn't kiss and tell, AJ knows how to sing a nice little song, and Tim Price The Podcrasher knows how to be a wonderful special guest for April's favorite episode.
