Real citation: "The L Word (Showtime) better bring back Dana Delany and fast. Playing a Senator on last night's episode, she was sharp, focused, and contained, packing more pow than all those younger actresses flopping their bodies and attitudes around.

Made-up citation: "Since getting a puppy, I have had less energy to pursue nookie-mashing activities, though the puppy is El Chick Magneto. It's a paradox."
