I'm looking to re-read the fic where Ryoga gets put through a lot,
and ends up working for Ukyou. I think He also gets a dunk in
the Nissanichawan (Beep Beep)

Anyone got a title or URL for that story?

Isn't this "The Adventures of Ucchan and Pchan"? If so, it's at
ftp://ftp.cs.ubc.ca/pub/archive/anime-fan-works/Ranma/
ranma.adventures-ucchan-pchan.gz
