Are You Smarter Than a 5th Grader? 8:00 pm ET

Host Jeff Foxworthy's folksy charm and the unaffectedness of the resident fifth-graders -- not a junior prima donna in the bunch -- have made this game show, starting a new season tonight with a two-hour episode, a hit with viewers. Of course, as "Who Wants to Be a Millionaire" reminded us, it's also great fun to watch grown-ups blow the answers to easy questions. Some, though, aren't so easy for folks 10, 20 or more years removed from elementary school.

Stand Up to Cancer 8:00 pm ET

Here's hoping people didn't get their telethon quota for the week from Jerry Lewis. This one, airing on ABC, CBS and NBC, is only an hour, but it packs a lot of star power into the time period and the cause: stepping up research into the causes of cancer and getting treatments to those who need them. Among the celebrities slated to appear are Jennifer Aniston, Lance Armstrong, Neil Patrick Harris, Hilary Swank and Sally Field.

Monk 9:00 pm ET

Who says you don't learn anything from television? In this new episode, Monk (Tony Shalhoub) is the subject of a TV show relating how he helped catch a serial killer. During a viewing party with the gang, Monk picks up a disturbing clue from the show: The third victim was killed by someone completely different. Traylor Howard and Ted Levine also star in "Mr. Monk's 100th Case."

The Astronaut Farmer 6:00 pm ET

Billy Bob Thornton gives a nicely understated performance in Michael and Mark Polish's gentle drama about a former NASA pilot who never reached his goal of going into space. He's determined to make up for that by building his own rocket and lifting off, much to the concern of government officials. Virginia Madsen ("Sideways") plays Thornton's wife. Bruce Willis and Bruce Dern also have supporting roles.

The Hitcher 7:00 pm ET

Sean Bean is no Rutger Hauer; then again, Rutger Hauer is no Cagney or Bogart. In other words, this 2007 remake of the 1986 thriller suffers from "making a copy of a copy" effect -- the quality only gets worse. And the idea that two road-tripping college students (Sophia Bush, Zachary Knighton) would offer an unsavory-looking stranger a ride in this day and age requires even more suspension of disbelief than it did in 1986. It's a scarier world out there, kids.

Samurai Girl 8:00 pm ET

Daddy's little girl ... not. This new miniseries tells the tale of a young woman (Jamie Chung, "Days of our Lives") who learns her adoptive father is the head of the Japanese mob and possibly the man behind her brother's murder. She trains as a samurai and makes it her mission to take down Daddy and his baddies with a little help from her friends. Brendan Fehr and Kyle Labine also star.

Swiss Family Robinson 8:00 pm ET

A couple and their three sons are shipwrecked on a deserted tropical island during a sea voyage from Europe to New Guinea. Despite wild animals and pirates, the family manages to make the most of its misfortune and create a personal paradise. This heartwarming 1960 movie stars John Mills, Dorothy McGuire, James MacArthur, Tommy Kirk and Kevin Corcoran.

The Dead Pool 8:00 pm ET

Folks are betting on when certain celebrities -- including rogue cop "Dirty" Harry Callahan (Clint Eastwood) -- are going to die, and somebody is taking steps to ensure they do. A film director (Liam Neeson) appears to be a likely suspect, especially when a rock star (Jim Carrey) whose video he's directing turns up dead. But as Callahan fans know, nothing is ever as it seems in Harry's world. Patricia Clarkson also stars in this 1988 actioner.

The Incredibles 8:00 pm ET

This is one family that won't have to worry about Halloween costumes. Once public superheroes, Elastigirl and Mr. Incredible settle down and recede from society's critical eye. But after three children and no action, Bob "Mr. Incredible" Parr gets restless and joins a secret organization. When he gets in trouble, it's up to his family to save him. Voices include Craig T. Nelson, Holly Hunter, Jason Lee, Spencer Fox and Sarah Vowell.

CBS Fall Preview 9:00 pm ET

Hang in there; the new shows are almost here. This special offers an overview of what's coming to the Eye network later this month. New shows premiering soon include the sitcoms "Worst Week" and "Gary Unmarried," the dating dramedy "The Ex List," the detective drama "The Mentalist," and the spooky "Eleventh Hour." Here, you can get more substantial samples than what the commercial-length promos provide.

DogTown 9:00 pm ET

What happened to Michael Vick's dogs after the Atlanta Falcons quarterback went to prison for running a dog-fighting ring? The answer is in the season premiere of this series set at an animal sanctuary in Utah: Twenty-two of them are here, learning to trust people and other dogs in hopes of finding them new, loving homes. The special two-hour episode focuses on four especially challenging dogs and the trainers working with them.

What Girls Learn 9:00 pm ET

They don't learn a lot, judging from the number of Lifetime movies in which they get in trouble. This isn't one of them, but it is a major downer. Based on a novel by Karin Cook, it tells the story of two Atlanta sisters (Alison Pill, Tamara Hope) coping with puberty, a new school and a new man (Scott Bakula, "Enterprise") in the life of their romantic, optimistic mother (Elizabeth Perkins). And then Mom gets cancer. Recommended only if you have something in your eye in need of flushing out.
