There's a ship meme going around and I feel like I need to explain myself before I put up my faves (and anti-faves). There are couples that I like, and there are ships that I like. I consider them two different things, though related. The difference between saying, "I *love* that couple," and "I totally ship them," has to do with competition. If the two characters ending up together is a foregone conclusion and there's never any uncertainty involved, I say I just love that couple - see Mr. Darcy and Elizabeth, Benedick and Beatrice, Turk and Carla on Scrubs, Marshall and Lily on HIMYM, Homer and Marge Simpson. All couples that I love, but I don't root for them because they're already together and there's no competition - it's not like we really have to worry about Mr. Darcy and Caroline Bingley. If I ship a couple, though, it's because there's either a viable romantic rival, they've broken up and there's an *actual* chance they won't work it out, or there's a chance that something will happen to one of the members of the duo before they can get together.

With all that said,

1) Barney and Robin, How I Met Your Mother. I'm not sure anyone has ever been more perfect for each other.
2) Ron and Hermione, the Harry Potter series. My two favorite ship kinks are "Hate turns into love" and "Best friends fall in love," and R/Hr have BOTH. (I don't believe JK Rowling ever had any intention of them ending up with anyone but each other, but I was very worried that one of them would die).
3 and 4) Xander and Cordelia, Buffy and Spike from Buffy the Vampire Slayer. I put them together because they're from the same show and I love them for pretty much the same reasons.
5) Joey and Pacey, Dawson's Creek. For such a cheesy show they really did make me believe in their love story.
6) Helo and Sharon, Battlestar Galactica.
7) Desmond and Penny, Lost - the only romantic relationship on the show the writers *haven't* managed to completely fuck up for me.
8) Angel and Darla, Angel. Not in the sense that I want them to be together forever, but in the sense that I enjoyed the hell out of them and they were HOT.
9) Daniel and Betty, Ugly Betty. Not that I've watched this show in forever but they're still hella cute.
10) Sandor Clegane and Sansa Stark, A Song of Ice and Fire series. You want a fucked-up ship? I'LL give you a fucked-up ship. I'm rooting for a dangerous insane beast of a man and a twelve-year-old virgin! In my defense, the story takes place in medieval times when twelve was, like, twenty. Plus, he totally saved her life, and Sandor/Sansa would be LESS creepy than Sansa and Joffrey or Sansa and Petyr Baelish (gag). Y'all totally need to read these books.

...I feel like I'm missing something really obvious and important.

As for my anti-ships, I think I hate most of the same ones as swsa and molly_may: Willow/Tara, Buffy/Riley, Carrie/Big, Juliet/Sawyer.
