Oh, David Foster Wallace... I've really enjoyed a few of his essays, and I thought I was safe when the longest sentence in the first paragraph of this one was a mere 43 words long. Then I got to the second paragraph, with its 130+ word sentence :/

This may perhaps be less edifying, but even more entertaining:
