TONIGHT'S MUST-SEE

"The Class," 7:30 p.m., CBS. Last week's episode ended with Richie deciding to make things right: He would break up with his sullen wife then tell all to his true love, Lina. Alas, it was too late. The wife was introducing herself to Lina. Now that continues tonight. Since Richie and Lina are played by the wonderful Jesse Tyler Ferguson and Heather Goldenhersh, expect good things. Meanwhile, Thanksgiving has Duncan bringing his mom to Nicole's house with Kyle and Aaron at Holly's home.

OF NOTE

"A Charlie Brown Thanksgiving" (7 p.m.) and "He's a Bully, Charlie Brown" (7:30 p.m.), ABC. First is a classic cartoon from 1973. Then there is a new one with Charlie confronting an arrogant marbles champion.

He was then a reporter, covering the story.
