Survivor: Micronesia -- Fans vs. Favorites: If this isn't the best Survivor ever, it's the best in a long time, with more injury-induced exits and blindside eliminations than the past few Survivors combined.

CSI: Crime Scene Investigation: In one of the most bizarre crossover stunts in TV history, CSI writers did the script for Monday's Two and a Half Men, which included CSI-style bodycams and a procedural-worthy twist. Tonight, Two and a Half Men writers return the favor and do CSI, in an episode in which Katey Sagal plays a sitcom diva found dead in Vegas. Two and a Half Men creator Chuck Lorre has been pretty open about his troubles with sitcom divas in the past, so expect him to exact some sweet revenge here. 8 p.m., KTVT/Channel 11
Supernatural: You know, I'm guessing that tonight's zombie-themed episode takes place in Erie, Pa., but given the creepy nature of this show, whoever spelled it "Eerie" in the CW synopsis can be forgiven for the error. 8 p.m., KDAF/Channel 33
30 Rock: As tends to be the case with season finales, it's a time of transition, with Jack (Alec Baldwin) finding out that his Homeland Security job isn't what he thought it was (Matthew Broderick plays a colleague), and Liz (Tina Fey, who deserves an Emmy for last week's episode alone) struggling with domestic and career crises. Edie Falco reprises her role as C.C., Jack's congresswoman ex. 8:30 p.m., KXAS/Channel 5
