Biggest Loser: Where Are They Now? (8pm, NBC) - NBC revisits more than 40 previous contestants from "Biggest Loser" to see how they've managed life off the ranch.
Criminal Minds (9pm, CBS) - The Reaper (C. Thomas Howell, left) returns tonight to terrorize Hotch and his family.
Glee (9pm, Fox) - Will believes Sue is leaking info about the glee club practices, so he visits with a rival club's instructor while the kids check out the competition. Also, Kurt has ulterior motives for giving Rachel a makeover.
Modern Family (9pm, ABC) - There has been a lot of buzz about this episode so I'm expecting greatness. Cameron makes a special appearance as Fizbo the Clown at Luke's big birthday bash. Eric Stonestreet, who plays Cameron, used to be a clown. For real.
Cougar Town (9:30pm, ABC) - This show seems to get a little funnier each week, especially with Busy Philipps (right) as Laurie "Seriously, I fight all the time" Keller. I mean, how can you not love a character who named her horse Limp Bizkit ... because he rocked. So it's a shame production has been halted due to a Courtney Cox "family matter." But let's live in the moment and enjoy Thanksgiving with Jules and the gang.
