Told my buddy Mark about this and he tried it with Rocko's Modern Life. He called me at midnight going off about how the background art has all these hidden adult jokes. He said it was like watching a different cartoon.

That green crust line is the exact thing I found on mine last year. It was on the hot water side, right where the pipe comes up through the slab. Did the plumber say anything about the rest of your lines being close to failing too, or was it just that one spot? I've been wondering if I should just replace the whole run now instead of waiting for the next one to pop.

Skip anything from strangers, that coffee spill thing is a classic red flag. Just hit up the art store next time.
