In the episode where Monica gets back together with Richard for a "friends relationship" and Pheobe dates the sporty guy who "pokes out" there are two slip ups. The first is when Rachel goes to borrow some ice from Joey. She twists the tray to get the ice free to put in her blender, but then when she leaves, the blender is empty. What happened to the ice?? The next is when Monica is waiting in Richards room. There are candles, wine and roses. When she realizes that he is home with another woman she blows out the candles and tries to hide. One of the candles on the dresser doesn't go out. It is then still lit, but then it is out. Hmmmm...
