Ok, here's my attempt:

-----------------------


(2 Ranma-chans in some sickenly obnoxious striped
pajamas sit on the porch of the Tendou home and mope.
One's pajamas is labeled R1, the other's R2.)

R1:  What do you want to do, R2?
R2:  What do YOU want to do, R1?
R1:  I'm not sure R2.
R2:  I'm not sure R1.

Akane, Shampoo, Ukyou, Kodachi (at once): WOULD YOU SHUT UP?!!!
YOU'VE BEEN USING THOSE SAME TIRED LINES FOR THE LAST FEW YEARS!
(they start after them with tooth and nails)

R1:  Are you thinking what I'm thinking, R2?
R2:  I think I am, R1!
Both:  (point their fingers in the air) It's FIANCEE AVOIDING TIME!

(Scene switches to Genma/Panda walking out of a room as R1 & R2 run
by quickly; the 'fiancees' give chase)

Mr. Panda: (sign) Why HELLO, R1 & R2!

R1: (racing past) Why, hello there, Mr. Panda, you old fudd!
R2: (same; mixture of sweetness and malice in her voice)
Mr. Panda, you've caused ever so much trouble!  I'm gonna *cream*
you when we get back!

Theme song starts as the Ranmas run back and forth avoiding the pain
following; Mr. Panda watches)

Bum bum bum dum dum dum---DUM!


<Verse 1>

Onnama Ranmas in Pajamas,
are hurtling down the stairs,

Onnama Ranmas in Pajamas,
are chasing a Panda Bear,

Onnama Ranmas in Pajamas,
were knocked through the air,
Hit by that silly panda who
caught them unaware!


<Verse 2>

Onnama Ranmas in Pajamas,
change when they get wet!

They're usually quite manly,
but now they're a bit upset!

Onnama Ranmas is Pajamas,
have haven't had a moment of peace yet!

Now they're wanted by every girl (and guy)
that they've ever met!


<Verse 3>

Onnama Ranmas in Pajamas,
Have got a stubborn fiance,

Onnama Ranmas in Pajamas,
are feeling a little blase,

Onnama Ranmas in Pajamas,
are about to be blown away,
by that stubborn girl, Akane,
with a mallet that's heavy-weighed!


ONNAMA RANMAS IN PAJAMAS 1/2!

          COMING SOON!
(maybe, if a time distortion ends up screwing the
boudries of Physical law on Earth, which creates a
large polar storm front that freezes Hell over)!
