What’s new tonight:

How I Met Your Mother (CBS) Halloween Episode: Katie Holmes guests as the legen … wait for it … dary “Slutty Pumpkin” that Ted’s been whining about losing for six seasons now. ---Equally mind-blowing, Barney learns that he’s part … Canadian! They’re dragging out all the scary shit tonight, eh.

Ghost Hunters Live (Syfy) Six-Hour Special: Wait, did you hear that? It’s 360 minutes of not finding a fucking thing—and getting paid for it! Well played, spook scammers.

The Bad Girls Club (Oxygen) Season Finale: The seventh BGC season in New Orleans has been somewhat of a disappointment, with no real breakout “stars” or new twists on the usual Crazy Drunk Bitches = Fistfight formula. If there’s going to be a Season 8, Oxygen should include a fully stocked gun case along with the fully stocked bar in the next mansion. I can’t be the first to think of introducing firearms, can I?

Rock Center With Brian Williams (NBC) Series Debut: Now that the nightmare of The Playboy Club (and, locally, We Are Utah) is over, here’s NBC Nightly News’ Brian Williams with … more news? Lifestyle features? Handsome tips? Given the name of the show, a re-imagining of Don Kirshner’s Rock Concert? (Google—sorry—Bing it, kids.) Not really sure what Rock Center is supposed to be, other than yet another primetime newsmagazine whose only distinctions are Williams, his Ocean’s Eleven lineup of correspondents (including Harry Smith, Kate Snow, Ted Koppel, Meredith Vieira, Richard Engel, Dr. Nancy Snyderman, Matt Lauer, Natalie Morales and Ann Curry) and a Halloween-night debut (which would have been a better slot for Grimm, but NBC knows what they’re doing … right?).

Also new tonight:
Scared Shrekless, Dancing With the Stars, Castle (ABC); 2 Broke Girls, Two & a Half Men, Mike & Molly, Hawaii Five-O (CBS); The Sing-Off (NBC); Terra Nova, House (Fox); Hoarders (A&E); Bachelorette Party: Las Vegas (Oxygen); The Real Housewives of Beverly Hills (Bravo); Ridiculousness, Death Valley, Cuff’d (MTV), Bored to Death, Enlightened (HBO)

Katie Holmes’ pumpkin doesn’t look all that slutty on HIMYM.
