Hi Opal!

What the hell is this “Hi Opal!” stuff I keep seeing on alot of the threads. Is this some kind of a Straight-Dope inside joke of some kind that I’m not getting, or is it something that is completely over my head?
Excuse my ignorance, but I must know what this means or I’m gonna go crazy the next time I see another one of these!
