Hmm, it probably depends what you think is weird, but I have one in their on the feasibility of extracting ammonia from biomass. There's also one on early steam turbines by a fellow named Geoff Horseman, which is a fun name.
Edit: Oh, I also have a professional critique of my dating profile photos. That's weird in a different way, since I actually got that done, and it unexpectedly came as a PDF.
