Make a list of all the characters in your icons. (Although you may have more than one icon of a single character, they only go on the list once.) Alphabetize it. Take the first two people on the list; that's your first pairing. Second two people; second pairing, etc. Treat us to some commentary once you're done.
I'm going to skip the alphabetizing part. I have too many old anime characters who I don't remember the names of. So mine will be in order of them on my user page.
+ = Big Bad Wolf + the girl who turns into a cat in that anime movie. I think the expressions say it all about this relationship!
+ = Dark + that guy from Prince of Tennis. Well, one of them seems happy about the upcoming pairing...
+ = Threesome time? Foursome? Moresome? One of the people involved is a young kid, another is his father, then toss in the two ninjas (one of which is a perv, if I remember correctly).
+ = A bunch of anime characters I don't recall! Red head was a kid and the girl seems kind of possessive, so I doubt this one would end well...
+ = Kyo (from Fruits Basket) + Professor Snape. Apparently Snape is a closet furry!
+ = I believe the soccer player was very underaged, which makes Gingi of the Get Backers's happiness a little worrying.
+ = Ken (from Digimon) and two more Naruto ninjas. Two of three people in this pairing are underaged! Bad what's your name, bad!
+ = I skipped any non-character icons (plain animals, people who aren't characters), but the white cat is a character from some anime movie (the same one as the brown catgirl?). Madam Hooch (from Harry Potter) is hooking up with a cat. Let's hope it's an Animagus!
+ = Ban (from Get Backers) with that guy I liked from Prince of Tennis. This looks like a good pairing, actually. Though the tennis fellow is a minor (actor playing him aside).
+ = Some anime character named Killua + FFXI Thistle. Cough. There goes FFXI Thistle hooking up with the half-cat people again! (Hi Nai!)
+ = Haku + Haku and Zazu(whatever his name was). There's likely already a fic with this "threesome" out there...
+ = PokeMUSH Thistle + Rita (from Animaniacs). Doesn't look like Rita's going to put up with any of Thistle's ecchiness! Rita is old enough and strong in character enough that she could likely stand up to PokeMUSH Thistle just fine.
+ = Chi + Aang (from Avatar). I do believe Poor Aang's ego is about to be crushed. By a kitten.
+ = Zuko + Haken. "You are of the living. You will not touch me. You will not have a relationship with me. You will be killed." *insert Zuko's expression here*
+ Keen + Penny (Thistle's wolf). WoW Thistle is going to have a Word with Keen... (Though Keen does already sleep with a worgen, so...)
+ (none left) = It's somehow fitting that WoW Thistle has no relationship. :P
(I left out all my FFXI alts (Fishingbot, Chaser) because if they ever had characters to begin with, I forgot them. Any duplicates I left out, and I used the first appearance of someone.)
