This probably makes me a giant nerd, but one of the things I most look forward to in December is the BMJ Christmas issue. I love that it's silly, but they still "do not publish spoofs, hoaxes, or fabricated studies." Side note, I also love their use of the Oxford comma.
This year, I particularly enjoyed their unsystematic review examining the poisonous plants of the holiday season and this interactive article inviting readers to spot real article titles vs those generated by AI. It's harder than you might expect.
