I can't figure out how to get the Onion Knight hat, my answer on SE meta became a c-w post on 23rd, which messed up my theory. The next day, it was deleted. Actually all the answers submitted to the Winterbash question were deleted. So, I can't complain... well, allow me to sniff and shed a tear.
So, I'm trying to test it elsewhere, but without luck...
Ha! Double ha! I may not have the burgundy balaclava but I have the mutiny hat, *Edward Edwards, 'tis even more gallant and rarer than the Onion Knight one.
