After words to the wise from Muammar Gaddafi's ghost, Charlie Day hosts, plays mediocre piano, and appears in sketches as Freakasaurus on Cee Lo Green's show, a reluctant audience member on Dr. Oz, Dionysus in a Mount Olympus parlay to sort out the Greek debt crisis, a comedian with a catchphrase, an actor working with a dolphin, and Colombo. Rick Perry explains himself on "Weekend Update," and Maroon 5 performs.
