How about someone taking the below scene and turning it into a fanfic?
(Yes, I know this scene has taken place with Nodoka instead of Genma, but
using Genma would have a totally different effect, don't you think?)  This
is not a short challenge (like the one hour challenge that was presented a
while back).

* * * * *

	"The reason I've called you all here," Genma said, looking at his guests,
which consisted of Ranma, Shampoo, Ukyou, Akane, and Kodachi, "is to make
an important announcement."

	"Well, get on with it already, oyaji," Ranma said, visibly annoyed at
having to listen to another one of his father's speeches.

	"Tendo, you may bring them in, now," Genma called out, ignoring his son's
disrespectful comment for the time-being.

	A few moments later, Soun, Nabiki, and Kasumi appeared, each pushing a
cart of some sort.

	"Ukyou, it was wrong of me to engage Ranma to you when he was already
engaged.  It was even more wrong for me to run off with the dowery like I
did.  These three fully stocked okonomiyaki carts should repay the dowery.
I'm sorry, but that is the best I can do.  With these, your engagement to
Ranma is now invalid."

	Ukyou jumped to her feet and whipped out her combat spatula, which Genma
quickly swiped from her and snapped over his knee.  "Sit.  Down," Genma
said sternly with an air of such determination that nobody had ever seen in
him before.  Needless to say, Ukyou quietly returned to her seated
position.  Shampoo and Kodachi, at hearing this began to grin madly.  One
of their rivals had just been taken out of the race.  Akane, for her part,
just sat there, a bewildered look on her face.  What was Genma up to.  A
similar thought was passing through Ranma's mind as well.


	"Shampoo, I had a very long discussion with Cologne yesterday.  Because
Ranma beat you first as a girl, you must kill him before you can marry him."

	Shampoo jumped to her feet.  "That stupid!  If Shampoo kill, then no can
marry!"

	"Right.  So your engagement to him is now invalid as well."

	"But--"

	"Shampoo...  Sit.  Down."

	Shampoo looked down at the floor as she regained her seated position.

	"Kodachi.  You are not Ranma's fiancee.  You never were.  Any claim you
may think you have on him is in your own deluded mind and is therefor
invalid."

	Kodachi glared daggers at Genma as she slowly rose to her feet.  "I,
Kodachi, the Black Rose, will never give up my love for Ranma-sama!"  With
that, she produced her whip out of nowhere and took a swipe at Genma with
it, who grabbed the end and gave a hard yank, causing her to stumble
forward.  Genma quickly raised his knee up and slammed it into her gut,
causing her to drop to the floor, clutching her stomach in pain.  Everyone
looked disbelievingly at Genma.  They never thought that he had either the
will nor the speed to do something like that.

	"Kodachi, go over there and sit down before I lose my temper."

	"Pop," Ranma said angrily as he jumped to his feet, "if you think that by
getting rid of all of my other 'fiancees', that you'll make me and Akane
get married, then you got another thing coming."

	"I'm not quite done yet, boy.  Sit down and shut up before I lose my
temper with you, too."  Ranma, for his part, just leaned against the dojo
wall and waited for his father to continue."

	"Have it your way.  Akane, since I engaged you to Ranma, I can also break
off the engagement, which I just did."  A gasp was heard from everyone in
the room except for Genma and Soun.  "Now, if one of you wants to marry
Ranma, you are going to have to win him over.  Each of you is on equal
footing now."  With that, Genma turned and left the dojo with Soun to go
cheat their way through another game of shogi.

* * * * *

	The reason Genma and Soun could do this is left up to you.  One idea I had
was that they wised up and realized that if they just backed off, Ranma and
Akane would pick each other of their own accord.  But, it's up to you.  You
can expand the scene above to meet your needs and change it as well.  The
only requirement is for Genma and Soun to agreed to nullify everyone's
claim on Ranma and it has to be clean.  By that I mean that Cologne can't
be still claiming that Ranma is engaged to Shampoo, etc.  You can make any
outcome you wish.  People can die, Ranma can choose anyone he wishes, etc.

Okay, everyone!  Start writing!  :)
