I think I've read a Ranma/Tick crossover before.  It was well written,
and it had Arthur as the main narrator.  I think it was called something

like

"Tales of an Arachnid" or something like that.  Am I hallucinating?

Foxtrot the Furryous, CBTFH, ret.

Well, it sounds like my Ranma 1/2:  Arthropod Antics...  I'm still working on
it, but it had been hiatus for a long time.  Now that I'm back online, I
should be getting out the next chapter soon...
