Into every family holiday gathering, a little TV viewing must fall. TheWrap's gift to you: a list of TV marathons lengthy and diverse enough to make sure everyone in the house has something to whet their appetites, TV-wise.
The lumpy mashed potatoes and dry turkey? You're on your own, there …
Doctor Who, 12 a.m.-9 p.m., BBC America. The marathon includes Who episodes and Best of installments on the Doctor's companions, monster foes and Christmas specials.
Harper's Island, 6 a.m.-7 p.m., Chiller. The entire 13-episode run of this 2009 CBS mystery series unspools. Trivia: cast members weren't told their characters were being killed off until the day they got the script for their demise episode.

Oddities, 6 a.m. Saturday-6 a.m. Sunday, Science Channel. Pickled hearts, mummified cats and monkey skulls are among the more normal goods bought and sold at Obscura Antiques & Oddities, the East Village NYC shop that is the setting for this series.
The Real Housewives of New Jersey, 6 a.m.-4 a.m. Sunday, Bravo. A chance to remember why you can't stand most of the cast members and why most of them can't stand each other now.
Jaws, 9 a.m.-4 a.m. Sunday, Spike. Curiously, Spike is airing the Jaws flicks out of order, beginning with Jaws: The Revenge, followed by Jaws 2 then Jaws 3 and the original movie at 7:06 p.m.
Mob Wives, 10 a.m.-4 p.m., VH1. Catch up with season one, because the gangster divas kick off season two on New Year's Day.
Roseanne, 10:30 a.m.-6 p.m., Oxygen. Still one of the best TV families, and the most underappreciated sitcoms, ever.
Planet Earth, noon-3 a.m. Sunday, Animal Planet. We never tire of watching this most amazing of nature documentaries.
Shark Marathon, noon-3 a.m. Sunday, Nat Geo Wild. If you can have Christmas in July, why not shark week, or rather day, in December?
Strangers With Candy, noon-4 p.m., Logo. The best sitcom ever about a 46-year-old high school freshman (Amy Sedaris) and the secretly gay history teacher/high school newspaper advisor (Stephen Colbert).
It's a Wonderful Lifetime, noon-4 a.m., Lifetime. A collection of holiday-themed made-for-TV chick flicks, including Holiday Baggage, Undercover Christmas and A Diva's Christmas Carol (which co-stars, randomly, Duran Duran bassist John Taylor).
Beavis and Butt-head, 4-9 p.m., MTV2. Uh, huh huh huh, you said ho.

Christmas Lights Marathon, 4-7 p.m., TLC. Includes Invasion of the Christmas Lights, Invasion of the Christmas Lights 2 and Crazy Christmas Lights.
The Devil You Know, 4 p.m.-6 a.m. Sunday, ID. It's not exactly in the spirit of the season, but this series -- about secret criminals and how their crimes affect their family and friends -- is addictive viewing.
Swamp People, 4 p.m.-4 a.m., History. Alligators and Cajuns are this year's Housewives.
Lockup, 6 p.m.-7 a.m. Sunday, MSNBC. The marathon includes a new episode of Lockup: Wabash - Extended Stay at 10 p.m.

Freaks and Geeks, 6 a.m.-noon, IFC. If only Netflix could jump in and reunite this cast for new episodes, as they're doing with Arrested Development.
House, 6 a.m.-6 a.m. Monday, Cloo. Just the thing for the hypochondriac at your holiday celebration (and every holiday celebration has one … at least one).
Secrets of World War II, 6 a.m.-3 a.m. Monday, Military Channel. Perfect for the military/war buff at your holiday celebration (and every holiday celebration has one … at least one).

The Oprah Winfrey Show, 10 a.m.-8 p.m., OWN. Missing The Big O? Yeah, she's missing ratings like the ones she used to get for these, episodes of her syndicated talk show.

Malcolm in the Middle, noon-12:30 p.m., IFC. Worth watching because it was a funny, clever show, and because it still amazes that Bryan Cranston could be this gifted a comedic actor and then so incredible as drug-making high school teacher Walt on Breaking Bad.
The Nutcracker, 12:30-10:30 p.m., Ovation. Includes The Nutcracker: Berlin State Ballet, Bolshoi Ballet: The Nutcracker, Mariinsky Theatre's Nutcracker and Nutcracker: The Story of Clara.

Band of Brothers, 9 a.m.-1:12 a.m. Tuesday, Spike TV. Homeland star Damian Lewis, Dexter baddie Colin Hanks, Shame star Michael Fassbender, new Justified cast member Neal McDonough, Southland star Michael Cudlitz and Blue Bloods cop/pop star Donnie Walhberg are but a fraction of the great cast in this 2001 Steven Spielberg/Tom Hanks-produced WWII miniseries.
I (Almost) Got Away With It, 9 a.m.-3 p.m., Discovery. Spoiler alert: the criminals in this show get caught. As you might have surmised from the title …
