Thanks for the memories, darlin’

Dallas Decoder kicks off its newest periodic feature, “The Dal-List,” with a look back at the 13 most memorable moments featuring “Dallas” vixen Kristin Shepard, played by the magnificent Mary Crosby.

Clothes call

13. Leaving Rudy. Feeling neglected by J.R. (Larry Hagman), Kristin turned to old flame Rudy Millington (Terry Lester) – and for a moment, it looked like she was going to allow him to make an honest woman of her. Then J.R. showed up, interrupting their post coital bliss. Before this embarrassing scene was over, Kristin had chosen J.R., leaving poor Rudy with a broken heart, no job – and possibly no pants. (“Return Engagements”)

Of vice and men

12. Scamming Judge Smith. A decade after Kristin’s death, an “angel” showed J.R. what life would have been like if he had never been born, including the revelation that Kristin became a cop. J.R. watched her bust grandfatherly Judge Smith (James T. Callahan) for solicitation – but it turned out the badge was fake: Kristin was really a con artist who preyed on powerful men. Guess she was destined to be bad. (“Conundrum”)

Daddy day scare

11. Bilking Jordan. After giving birth in California, Kristin sashays back to Dallas and makes a phone call. “The baby … looks just like you,” she coos. The audience is led to believe the person on the other end of the line is J.R. – so imagine our surprise when it turns out to be rival oilman Jordan Lee (Don Starr). It seems Kristin lied to Jordan, telling him he was her child’s father – just so she could bilk him for hush money. (“Full Circle”)

Buckle up, Bob

10. Charming Bobby. Kristin (Colleen Camp) paid her first visit to Southfork just as Bobby and Pam (Patrick Duffy, Victoria Principal) were hitting a rough patch – so J.R. naturally encouraged his wife’s little sister to seduce his baby brother. Kristin obliged, charming Bobby with her clever wit and tight sweaters. Then Bobby and Pam made up, leaving Kristin free to pursue the brother she wanted all along. (“Sue Ellen’s Sister”)

See what develops

9. Exposing Lucy. The only person Kristin despised more than Lucy (Charlene Tilton) was J.R.’s protégé Alan Beam (Randolph Powell), so when Kristin saw Lucy and Alan canoodling at a roller disco, she did what came naturally: She reached for the nearest Polaroid and started snapping pictures. Kristin hoped exposing Lucy and Alan’s secret affair would get them in trouble. It didn’t work out that way, but it still caused lots of drama. (“Power Play”)

Lap it up, Val

8. Befriending Val. After wearing out her welcome in Dallas, Kristin headed to Knots Landing, where she got busy wrecking the marriage of those nice young suburbanites, Kenny and Ginger Ward (James Houghton, Kim Lankford). Soon, Valene (Joan Van Ark) was confronting Kristin, who confessed she was pregnant and afraid for her future. It was a rare and moving glimpse into Kristin’s soul. Who knew she even had one? (“Kristin”)

Sister, sister

7. Taunting Sue Ellen. Sue Ellen (Linda Gray) was suffering major post-partum depression when Kristin started flirting with J.R. So you couldn’t blame big sis for being suspicious when Kristin popped into her bedroom one evening to see if she’d be joining the rest of the family for dinner. “Were you thinking of occupying my chair?” Sue Ellen seethed. “Somebody will if you don’t pull yourself together,” Kristin sneered. (“The Silent Killer”)

Spill life

6. Drenching Sue Ellen. Oh, look: Sue Ellen and Kristin are in a posh restaurant, toasting their renewed friendship. Nice to see them getting along, isn’t it? Whoops, klutzy Kristin just spilled her cocktail in Sue Ellen’s lap. If she’s not careful, the Ewings are going to smell the booze and begin to suspect Sue Ellen has fallen off the wagon. Wait, what’s that you say? That was Kristin’s plan all along? What a hussy! (“Divorce, Ewing Style”)

If smirks could kill

5. Seducing J.R. Once J.R. hired Kristin as his new secretary, it didn’t take her long to figure out his scheme to secretly mortgage Southfork. She threatened to spill the beans to Jock and Bobby – unless J.R. slept with her. Turns out she didn’t need to ask twice. “Kristin,” J.R. said as he took her in his arms, “with your mind and your body, it just might take me a lifetime to figure you out.” Cost him his life is more like it. (“The Kristin Affair”)

Move over, Florence Nightingale

4. Mocking J.R. While recovering in the hospital from his shooting, J.R. was surprised to receive a visit from Kristin, who was still in town after his goons failed to run her off. “Don’t you worry, Kristin. When I get out of here, you’ll get yours,” J.R. warned. “I know I will,” she smirked as she looked his paralyzed body up and down. “But not from you. That’s for sure.” J.R.’s under-his-breath response after she left the room: “Bitch.” (“Nightmare”)

Is it really that black and white?

3. Scandalizing J.R. After giving birth to the son she claimed was J.R.’s, Kristin showed up at Southfork demanding more “child support.” Next thing you know, Cliff was fishing her dead body out of the swimming pool and claiming J.R. had murdered her. Before all was said and done, J.R. was being hauled into court to prove his innocence. Even in death, Kristin was still causing him trouble. That’s our girl! (“Gone But Not Forgotten”)

She bangs

2. Shooting J.R. No one knew whodunit when J.R. was gunned down in his office. Then the weapon was discovered in his bedroom closet. The cops arrested Sue Ellen, who figured out Kristin was framing her and made little sister confess. Of course, Kristin had a get-out-of-jail card: She was pregnant with J.R.’s love child. Fed up with her drama, J.R. finally exiled Kristin to California. Too bad she didn’t stay there. (“Who Done It?”)

Wait ’til you see him grown up!

1. Birthing Christopher. OK, we never actually saw this on screen, but so what? After miscarrying J.R.’s baby, Kristin got pregnant by sleazy Jeff Farraday (Art Hindle), who sold their child, Christopher, to Bobby after Miss Shepard took her deadly dive into the Southfork swimming pool. So when you think about it, Kristin is responsible for giving us Jesse Metcalfe on TNT’s “Dallas.” If that’s not a crowning achievement, I don’t know what is.
