Like everyone else I've been reading bobince's outbreak about parsing html with regex with great amusement. When I read in the comments that bobince had been awarded two gold badges (html and regex) for this single post, something occured to me. What would happen if I edited the question and added another tag? Unable to resist the urge I appended the "parsing" tag to the OP.
It took a few hours, but sure enough. bobince is now proud owner of the gold medal "parsing" badge. That means that we currently have a mechanism that allows any owner of a 1000+ votes post to receive any tag gold badge they'd like, and even funnier is the fact that anyone else can reward them with an arbitrary gold medal.
