This is just a little fun for a Friday.
My critique group has played with Tandem Writing exercises. One was called 
One Immortal Too Many. It was a combination of 
Highlander, Lonesome Dover, The Outlaw Years, and 
La Femme Nikita. That was a long time ago, and I'd forgotten about it until I came across this EMail someone sent me.
It shows that tandem writing can go very wrong. Take a look at this supposedly real exercise that was turned in when an English teacher randomly paired students:
THE ASSIGNMENT: Today we will write a tandem story in pairs.  One of you  will write the first paragraph of a short story. The partner  will continue the story by writing the second paragraph. The first person will write the third paragraph, and so on back and forth. Keep the flow going for a coherent story.
THE RESULT submitted by "Rebecca" and "Gary:"

Rebecca: At first, Laurie couldn't decide which  kind of tea she wanted.  The camomile, which used to be her favorite for  lazy evenings at home, now reminded her too much of Carl, who once said, in  happier times, that he liked camomile.  But she felt she must now, at all  costs, keep her mind off Carl.  His possessiveness was suffocating,  and if she thought about him too much her asthma started acting up again.   So camomile was out of the question.
  
Gary:  Meanwhile, Advance Sergeant Carl Harris,  leader of the attack squadron in  orbit over Skylon 4, had more  important things to think about than the air-headed asthmatic  bimbo named Laurie with whom he had spent one sweaty night over a year  ago.  "A.S. Harris to Geostation 17," he said into his  communicator.  "Polar orbit established.  No sign of resistance so  far...".  But before he could sign off a bluish particle beam blasted a hole through his ship's cargo bay.  The jolt  from the direct hit sent him flying out of his seat and across the  cockpit.  
Rebecca: He bumped his head and died almost  immediately, but not before he felt one last  pang of regret for  psychically brutalizing the one woman who had ever had  feelings for  him.  Soon afterwards, Earth stopped its pointless hostilities towards the  peaceful farmers of Skylon 4.  "Congress Passes Law Permanently Abolishing  War and Space Travel."  Laurie read in her newspaper one morning.  She stared out the window,  dreaming of her youth -- when the days had passed unhurriedly and carefree, with  no newspapers to read, no television to distract her from her sense of innocent  wonder at all the beautiful things around her.
  
Gary: Little did she know, she had less than  10 seconds to live.  The dim-witted peaceniks who'd passed the Aerospace Disarmament Treaty had left earth a defenseless target for aliens. Thousands of miles above the city, the Anu'udrian  mothership launched the first of its lithium fusion missiles.   The  missile entered the atmosphere unimpeded. The President, in his submarine headquarters off the coast of  Guam, felt the massive explosion which vaporized Laurie and 85  million other Americans. "We can't allow this!" the President declared. "I'm going to veto  that  treaty!  Let's blow 'em out of the sky!"  
Rebecca: This is absurd.  I refuse to continue  this mockery of literature.  My writing partner is a violent, chauvinistic,  semi-literate adolescent.  
Gary:  Yeah?  Well, you're a self-centered  tedious neurotic whose attempts at writing are the literary equivalent of  Valium.  
Rebecca: A-hole.  
Gary: Bitch.

Happy writing and reading.
