I got this revelation from posting on BeAStooge's thread of 45 years of Batman ...
We have danced around and posted these things for Stooge eons, but never in a concise thread.
Here's my first entry:

Moe: It means you need to wash your hands!
I've started this thread without substantiating my post because I'm using my warped and failing memory. I'll work on posting its origin.
