How Friday's fare fared:
Ghost Whisperer's season finale scared up 8.93 million total viewers, dipping 5 percent week-to-week. America's Funniest Home Videos' own season-ender placed second with 5.64 mil, followed by Dateline.
Prison Break's final farewell drew 3.33 mil, up 10 percent, while The Game blew the whistle on its own season with 1.86 mil. (And yes, that episode was a taste of how the show would work as a single-camera, hour-long dramedy.)
NBC's Farrah's Story doc averaged 8.94 million viewers over its two-hour run, and topped the 9 o'clock hour. Flashpoint followed with 8.42 mil.
Numbers was the night's most watched program, scoring 9.6 million viewers for its season finale.
Saturday Night Live, hosted by Will Ferrell and featuring musical guest Green Day, matched the show's year-ago closer to equal its best overnight rating for a season finale in four years. The last SNL finale to rate higher was the May 21, 2005 telecast hosted by Lindsay Lohan.
