"Saturday Night Live" cast member Andy Samberg says he won't be returning to the show next season. Samberg has been a regular on the late-night NBC sketch comedy program since 2005. A number of songs crafted and performed by Samberg and his fellow cast members have created sensations over the years, beginning with "Lazy Sunday." The song featured Samberg and Chris Parnell rapping about buying snacks and going to see the movie "The Chronicles of Narnia." He's also appeared in a number of movies, television shows and as a voice actor in animated films. Samberg said the decision represents "an incredibly emotional and strange moment" in his life.
