Look back

Did you promise yourself you’d spend the summer getting acquainted — or reacquainted — with TNT’s “Dallas”? Did you fail to keep this promise? Relax: You still have time. Grab your DVDs and downloads and have a marathon of your own this weekend. Here’s how to watch all 33 hours of the show before the third season resumes on Monday, August 18.

Friday, August 15

9 to 11 p.m. Kick off your marathon on Friday night at 9 o’clock — the holiest hour of the week for “Dallas” fans — with a double feature of the TNT’s show’s first two episodes: “Changing of the Guard” and “Hedging Your Bets.”

Can you watch the former without getting chills when J.R. (Larry Hagman) doffs his cowboy hat, flashes his grin and declares, “Bobby may not be stupid, but I’m a hell of a lot smarter”? Can you watch the latter without getting choked up when our hero tells Sue Ellen (Linda Gray) she’s “still the prettiest girl at the ball”? Me either.

First time for everything

Saturday, August 16

7 a.m. Rise and shine, darlins! With so much “Dallas” to watch today, there’ll be no sleeping in. Resume your marathon with “The Price You Pay,” in which Julie Gonzalo’s character receives a smartphone pic of her husband kissing another woman. Get used to it, honey.

8 a.m. Have breakfast with “The Last Hurrah,” in which John Ross (Josh Henderson) squirts Elena (Jordana Brewster) with his hose. Insert your own joke here.

9 a.m. Have you done your workout yet? Download “Truth and Consequences” to your mobile device and head to the gym. Mitch Pileggi’s debut as Harris Ryland is bound to get your heart racing.

10 a.m. Got errands to run? Chores to complete? You’ve got one hour. Make the most of it.

11 a.m. We learn jewelry makes Ann (Brenda Strong) cry in “The Enemy of My Enemy.” Then again, doesn’t everything?

Noon. Grab lunch while watching “Collateral Damage,” in which Vicente Cano (Carlos Bernard) wonders if John Ross: 1) is a good dancer, and 2) has any oil in his pipeline. OMG, Vicente was such a flirt!

1 p.m. Tommy (Callard Harris) plants a kiss on Rebecca in “No Good Deed” — which is almost as creepy as when Nicolas starts smooching Elena in Season 3.

2 p.m. Bloody monkeys, Johnny Cash and the redemption of J.R. Ewing. It’s “Family Business” — one of my favorite episodes of this show.

3 p.m. Carmen (Marlene Forte) gets one of the crummiest chores in “Dallas” history — returning Elena’s engagement ring to John Ross — in “Revelations.” Also: More Johnny Cash!

4 p.m. Have you taken a bathroom break yet? If not, take care of that now, and then hurry back to your TV or tablet to watch the second-season opener, “Battle Lines,” in which Christopher (Jesse Metcalfe) learns his wife is really his cousin. Ick.

5 p.m. In “Venomous Creatures,” J.R. saves Sue Ellen from going to jail and Judith Light discovers a taste for “Dallas” scenery.

6 p.m. Drew (Kuno Becker) arrives in “Sins of the Father” — his hair won’t show up for several more episodes — and calls John Ross “J-Ro.” Thank heavens that didn’t catch on. Also: Ann shoots Harris!

7 p.m. Has your family seen you at all today? Why not take a break from the Ewings and go have dinner with them.

8 p.m. to midnight: The next four episodes are a murder-a-thon, so brace yourself. Frank (Faran Tahir) offs himself in “False Confessions,” Brenda Strong kills it during Ann’s testimony scene in “Trial and Error,” Vicente bites the dust in “Blame Game,” and then the saddest shot of all: the death of J.R. Ewing in “The Furious and the Fast.”

Midnight. The nice thing about a late-night viewing of “J.R.’s Masterpiece” is that no one else in your house is awake to see you bawling. Once you’ve dried your tears, catch some shut-eye. Tomorrow is going to be another big day.

Leg up

Sunday, August 17

8 a.m. You did a hell of a job yesterday, “Dallas” fan. Your reward: You get to start your Sunday with the wonderfully wacky hodgepodge that is “Ewings Unite!” Miss Ellie disinherits Bobby from beyond the grave, Valene (Joan Van Ark) reveals she’s as loony as ever and Cliff becomes the most hated man in the history of “Dallas” fandom.

9 a.m. Audrey Landers shows she can slink around a corner better than anyone in “Guilt and Innocence.”

10 a.m. In “Let Me In,” Harris reveals his fondness for: 1) TV nature documentaries, 2) Almonds, and 3) Hunting Ramoses.

11 a.m. John Ross and Pamela get wet in “A Call to Arms.”

Noon. You know what goes good with a nice, leisurely Sunday brunch? Watching Bobby take that badass, slow-motion walk away from Cliff at the end of “Love and Family.”

1 p.m. Christopher discovers the mystery lady under the big hat is not his mama in “Guilt by Association.” It’s not Aunt Katherine either, sadly.

2 p.m. Kevin Page joins Mary Crosby as an answer to “Dallas’s” most famous trivia question in “Legacies.”

3 p.m. You might think this would be a good time to take a break, but you’d be wrong. The die is cast and there’s no turning back, so keep plugging away with the third-season episodes, beginning with “The Return,” in which J.R.’s belt buckle begins wearing John Ross. Also: Hello, Nicolas (Juan Pablo Di Pace)!

4 p.m. Time for “Trust Me” a.k.a. “Judith’s Snow Day.”

5 p.m. In “Playing Chicken,” Professor Bobby Ewing teaches us about endangered wildlife.

6 p.m. “Lifting the Veil” is the episode that should’ve included Sue Ellen’s comparison of Emma (Emma Bell) to Kristin, but instead it’s the episode that gives us scenes of hookers in canine costumes.

7 p.m. Dinnertime! Enjoy a glass of J.R. Ewing Bourbon (surely you have some, right?) while watching “D.T.R.” After the episode, check your bottle and make sure Sue Ellen didn’t bug it.

8 p.m. Despite the title “Like Father, Like Son,” John Ross wants you to know that he is not his father! Also: Carter McKay has grandchildren!

9 p.m. Pamela rocks Stella McCartney in “Like a Bad Penny.”

10 p.m. It’s finally time for “Where There’s Smoke.” Southfork goes up in flames and you get to go down for a well-deserved rest. Don’t forget to watch “Dallas’s” midseason premiere Monday night!
