In the old days in California there was a saying:
“If it’s yellow
Let it mellow
If it’s brown
Flush it down”
Seems like a cheaper alternative.

Then, on a washroom wall in Arizona:
“Flush twice
It’s a long way to L.A.”

What the heck does “let it mellow” mean? How yellow should it be before we flush it?
