The Reference Explanation Thread

[Nate the Great]

Not even remotely. It's a reference to a very fine miniseries called The Magical Legend of the Leprechauns. At one point a group of leprechauns are going to a floating castle by riding inside a soap bubble (leprechauns can't fly, remember?), and one says "What's that smell?" Another says "That's clean. You wouldn't have smelled it before." It's a comment on leprechaun hygeine. This is a reference that I only included for my own sake, and I knew going in that nobody would get it. The habits of Klingons regarding cleanliness just seemed like a great place to indulge myself. Plus, I get the additional joy of implying that Kang may have been "softened" a bit by his interactions with humans by at least learning subconciously to distinguish between dirty smells and clean smells.
