It's nonstop laughs in this 33rd season of "SNL," which kicks off with NBA hoopster LeBron James as host and closes in May 2008 with host Steve Carell of "The Office." Other guests include Seth Rogen, former "SNL" cast member Tina Fey, Ellen Page, Ashton Kutcher, Jonah Hill and the ever-present Christopher Walken. A notably shorter season, "SNL" aired only 12 episodes due to the Writers Guild of America strike.
