Zach Weiner's Saturday Morning Breakfast Cereal is consistently one of the funniest and most intelligent webcomics available. Today's, though, was especially good. A Nineteenth Century British owner of an analytical engine is contacting tech support, which apparently wasn't any better back then.
I would like to add that Mr. Weiner is a gentleman. A year or so ago, I emailed him, asking for permission to use one of his cartoons for a project at my day job. He responded favorably in literally under a minute, and even offered to track down and send a high-resolution version of the cartoon in question.
