I didn't have a book with me on the bus today so I had to compile this list instead. Who have I missed out? Tell me!
1. Beatrice and Benedick - Much Ado About Nothing. They hate each other! But they love each other really!
2. Mulder and Scully - The X-Files. Aw, they are so touchy feely. And yet not Doing It. Until they are. Or are they? I don't know, I gave up when David Duchovny stropped off.
3. Holmes and Watson. You can't tell me they are not a couple. Well, you can and you'd have some evidence on your side, like Watson's (two?) marriages. But they are, you know. IN MY HEAD.
4. .Jane Eyre and Mr Rochester - Jane Eyre. The model for many a future Mills and Boon.
5. Elizabeth Bennett and Mr Darcy - Pride & Prejudice. Yes, obvious, but I like Elizabeth, so shut up.
6. Scarlett O'Hara and Rhett Butler - Gone With the Wind. Oh Scarlett, can't you see Rhett loves you, not that drippy Ashley? Luckily all's well that ends well, if you believe Scarlett and wait until Rhett is practically ninety or something.
7. Spike and Buffy, Buffy the Vampire Slayer. He loved her so much he got a soul! Unlike Angel who had to have one forced on him, and still can't keep hold of it for more than about five seconds. Also, much better chemistry.
8. Katherine and Vincent, Beauty and the Beast. He comes from a secret world far below the city streets! She, er, something about her world, a world apart from his. They cannot be together (because he looks like a lion?) but they will never, ever be apart!
9. Jo March and Laurie Lawrence, Little Women. I don't know what Louisa Alcott was thinking pairing Laurie with Amy in the end. It just results in a union of unbearable smugness - and Bess.
10. Lord Peter Wimsey and Harriet Vane. I can't believe I forgot them. I love Harriet. And they are proof that you can still be an interesting couple once married, although admittedly only just so.
[edited to get rid of Lois/ Clark - peter and Harriet are much sexier]
And two that nearly made it but I thought were a bit obscure, also I can't remember the names: Girl and Sorry (?) in The Changeover (they are telepathic!); Girl and Robot in Silver Metal Lover (good to have obstacles in the path of true love, and what better obstacle than one of you being a robot?).
I'm sure there are loads I like better then these, especially Little Women and Superman, but I can't think of them right now.
