Regarding my class's patch...
1) Yes, we had two Japanese studs, one Slovak and the first Afghan to receive training here in the States. All were really good dudes. There were definitely cultural issues with the Afghan, but he's motivated and works hard. The Slovak and he are ALP studs and should be out of here in a couple months.
2) The original patch was as pictured in the link, but it had "one taco at a time" on a second line. Obvious double entendre, right? We submitted it up the chain and MEO disapproved it because it could be considered offensive to hispanics (no mention of the world's 3 billion women). So we removed that line, resubmitted and... shazzam. Approved! We wore it for a few months and eventually the jig was up. Word came down quickly that we were to remove it under threat of LOR. My SRO got reamed for it. We submitted another patch (donkey punch theme), had that shot down and were subsequently assigned a patch... a gray square with our class number in the middle in black... 3" on all sides. We'll be wearing that proudly until we graduate.
But mustaches! The majority of my class will be rocking a 'stache for the month... some better than others, of course.
