oh yes..grog and grog bowl...i remember it well
I was at the table at a dinning in with my NCOIC and my supervisor. For some darn reason, my bowtie kept falling off into my plate while i was eating. Since one of the rules of the mess was "That your uniform must be to standards" My NCOIC noticed it kept falling off, and turned around to inform the mess of the situation. Between the time he was speaking to the mess and their reply, my supervisor grabbed the tie and taking a safety pin out of his pocket, rapidly pinned it back into place. When the mess directed their attention to the evidence...well it wasn't in the plate anymore.
He went to the grog bowl twice that night..once for reporting an obvious non-discrepancy...and later on when he told the spokesman of the mess where he could stick his own bowtie...
We all did have fun that night...
