Um, I think we're all missing something here. Like the beginning:
--------
(A seashore. Some way out to sea a small piglet with a yellow and
black striped bandanna is struggling his way to shore, dragging
along a large backpack full of stuff. Slowly and difficulty he
makes his way up onto the beach. He disappears for a few moments
as he crawls beneath the view of the camera. Steam rises, and a
tired and bedraggled Ryouga struggles up into camera range and
announces:)

Ryouga <himself>: It's...


            RANMA PYTHON'S FLYING CIRCUS

--------
This is about as far as I've gotten. Except for some replacement thingies
from a fic that I started three years ago but dropped, which is a straight
rip-off of the regular show, but with a twist:
--------
(Ordinary grey-suited announcer standing by desk (or rather, ON
the desk). He smiles confidently.)

Announcer <Happousai>: Good evening.

(Announcer confidently moves to the chair and sits down. There is
a squeal as of a pig getting sat on.)

(Cut to blackboard with several lines of P-chans drawn on it. A
woman <Akane> steps into view and crosses one out with a piece of chalk.)
--------
Mozart: Thank you, Eddie. And now time for this week's request
	death. (taking card off piano) For the greater female popu-
	lation of Nerima prefecture of Japan, the death of Happousai.

(Rooftop, Happousai laughing and jumping with his usual sack.
Stops and looks shocked toward camera.)

Happousai <himself>: Strewth! (he dies)

(Cut to stock film of women applauding. Cut again to Tendou home,
where Tendou Soun <himself> and Saotome Genma <himself> clink two
Champagne glasses together.)
--------
Well, I hope you enjoyed that. Even if it wasn't too original, it's still
drawing a few chuckles out of me even now.
