This Week in TV: Beavis, Butt-head, Obama on Leno and Snoopy and Bart Simpson Provide Tricks & Treats

President Obama also makes his fourth visit to “The Tonight Show”

What all the TV-loving kids will be talking about this week …

And not a moment too soon. The wise-cracking Texas teens left the MTV airwaves in 1997, which means they've been MIA for most of the reality TV explosion. How nice, then, to have them back in time to poke fun at shows like their MTV brethren, "Jersey Shore" and "16 and Pregnant."

Series creator Mike Judge has created 12 new episodes of "Beavis and Butt-head," and though nothing about the boys' behavior (or clothing) has changed, they are living in modern times. In the season premiere, for instance, the popularity of "Twilight" makes them think they'll be popular with the ladies if they become vampires.

Their bright idea for achieving that: Coaxing a werewolf to bite them. Of course, the "werewolf" turns out to be a homeless guy with hepatitis C.

"Beavis and Butt-head" returns Oct. Thursday at 10/9c on MTV.

NBC's "Chuck" has survived for four seasons on the network, thanks to multiple "save our show" campaigns from its devoted fanbase. So, though the show begins what is definitely its fifth, and final, season on Oct. 28, at least the cast and crew will get the chance to wrap up their storylines, something that was perpetually in question during the show's ratings-rollercoaster run.

As for this final season, producers Josh Schwartz and Chris Fedak have cooked up a plot that should make most of the viewers who've stuck with the action-comedy (and ate a lot of Subway sandwiches to save it) happy.

Newly wealthy Chuck and Sarah are now the owners of the Buy More and the operators of a freelance spy org called Carmichael Industries. John Casey and Morgan — the new Intersect — work for them, and one of Chuck's main duties is to keep Morgan safe.

Also on tap for the new season, the series will continue its tradition of using a plethora of guest stars, and season five's lineup includes Mark Hamill, Bo Derek, Craig Kilborn, Carrie-Anne Moss, David Koechner, Danny Pudi, Rebecca Romijn, Stan Lee and Cheryl Ladd.

"Chuck" returns Friday at 8/7c on NBC.

Do we wish President Obama was sitting down to chat with Conan or Craig Ferguson instead, while he's on the west coast? Of course. But the POTUS has chosen Tuesday's "The Tonight Show with Jay Leno" for his late-night drop-in, where he and the host will chatter about Obama's re-election bid and his jobs bill.

The guest appearance will be Obama's fourth on "The Tonight Show," and his second since taking office.

President Obama appears on "The Tonight Show" Monday at 11:35/10:35c on NBC.

This year marks the 45th anniversary of the debut of the Halloween Peanuts special "It's the Great Pumpkin, Charlie Brown," and blanket-toting Linus still hasn't been deterred: He's sure the Great Pumpkin will fly "through the air and (bring) toys to all the children of the world."

Charlie Brown still holds out hope of getting something other than rocks in his trick-or-treat bag, too, but, like Lucy with the football, a fruitful candy-collecting excursion is just not meant to be for the zig-zag-shirted one.

"It's the Great Pumpkin, Charlie Brown" airs Thursday at 8/7c on ABC.

Another Halloween treat for TV viewers this year is that the annual "Treehouse of Horror" installment of "The Simpsons" will actually air before the holiday (the episodes have aired in November for 10 of the past 11 years).

Kang and Kudos return, as always, for "Treehouse of Horror XXII," which offers Ned Flanders as a serial killer (in "Dial D for Diddly"), Bart and Milhouse searching for a rare extract in outer space (in the "Avatar"-spoofing "In the Na'Vi" segment) and a paralyzed Homer only able to communicate via his "natural gas" (in "The Diving Bell and Butterball").

"The Simpsons" airs Sunday at 8/7c on Fox.
