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.
I included cartoon and comic characters, just to make it more cracktastic. And I alphabatized by first name only because I had several people with the same last name and who really wants to see the canon pairing of Sarah and Walt Bannerman? Not me.

Pairings:
Adina/Allmighty Tallest Purple
Purple is voiced by Kevin MacDonald of Kids in the Hall fame. I think he and Adina would be very funny together.
Almighty Tallest Red/Benton Fraser
Well at least they'd match what with all the red.
Carson Beckett/Charlie Epps
Not a part of my Numb3rs/Atlantis xover, but intriguing none the less.
Charlie Pace/Crow
Charlie could appreciate Crow's off beat humor. I think he'd enjoy MSTing movies.
Daniel Jackson/Dave Dixon
Of course Daniel would want to have sex with Dave. Everyone else in the SG-15 universe does!
Dean McDermott/Diefenbaker
I probably should have left the wolf off the list right? Poor Dean. I love you! I'm sure he's soft hearted enough to give Dief plenty of snacks.
Don Epps/Elizabeth Weir
Interesting.... These two probably would get along.
Ewan McGregor/Gir
LOL! These two are a lot alike in a random crazy kind of way. Plus, Gir would love racing motor bikes with Ewan, though he'd probably make fun of his accent. I can here it now. "You talk funny! Let me sing you the Doom Song!"
Gonzo the Great/Greg House
OMG could you just see House on The Muppets? Bwa! If I was going to pair House with a puppet, it'd have to be Oscar the Grouch.
Harry Maybourne/Hermiod
Not impossible. Highly disturbing though.
Jack Knight/Jack O'Neill
Hey a comic book/SG-1 xover that would work. Ted Knight's work with the military making an impression on a young Jack O'Neill. Many years later, Starman runs into alien trouble and in comes SG-1. Two cynical humors bouncing off each other. It could work.
James Wilson/John Sheppard
James has always had a thing for guys in uniform. A quick look around the bar, and he knows who he's going to be spending the night with. The guy isn't wearing a uniform, but it's written all over the set of his shoulders when another guy gets tough. Words are exchanged, fists fly, and the bouncer breaks it up. James slides over and offers his expertise with a bloody nose. The grin he recieves is nice, but the eyes are dark and full of mystery. It makes him think too much about Greg, so he does his best not to look directly into the hazel orbs again. The guy doesn't seem to mind when he offers James a ride home. He never bothers to ask about the ring around James' finger either. Everyone knows how to play this game, and after all, it's only for one night.
Johnny Smith/Kavanaugh
Wrong, wrong, wrong... maybe the reason Kavanaugh is such an asshole is because Johnny forsaw his death in Atlantis? Who knows?
Kermit the Frog/Larry Fleinheart
It's disturbing how this kind of works. Really disturbing.
MacGyver/Martouf
Hell, why not?
Radek Zelenka/Ray Kowalski
You know this would be cute if it was set when they were younger.
Renfield Turnbull/Rodney McKay
The Canadian love man! Hee! I would pay
heuradys money to write this. I really would. I can see it now. Canada's asset Rodney McKay needs protection... it's just they don't like him so they assign the new guy too him. Let the comedy and porn commence!
Sam Carter/Sarah Bannerman
Hey two of my shows annoyances together. They'd probably get along.
"Sawyer" James Ford/Spike
Easily see this. Too easily.
Teyla Emmagan/Walt Bannerman
I have no idea of how this would work, but bonus points if Teyla beats him up a little first.
Zim... doesn't get anyone...which is only right.
