Always label your axes
From Fluffware, here's a fine reminder to always label your axes. See, it's funny because usually when we talk about labeling axes, we're talking about axes on plots for context, but here axes is used as the plural of axe, so there are labels on several axes. It's a play on words. More specifically, it works because axes on a plot and axes the wood-cutting tool are homographs. They're two words with the same spelling but are pronounced differently. So the joke works with the written word, but it would not work if I were to tell it to you in person. Just to be clear, you should always label both types of axes. Tool and plot, that is. I mean, let's say you asked someone who only knew about axes (the plot kind) to fetch a certain type of axe (the tool) from your woodshed. If you didn't label your axes (the tools), that person wouldn't have a clue. That'd be embarrassing for both parties. And don't even get me started with the spray.
