Days after AI Overviews rolled out to all U.S. users, it surfaced answers drawn from satire and joke forum posts, such as adding glue to pizza sauce and eating a small rock daily. Google said many viral examples were fake but made more than a dozen fixes, including limiting satire and user-generated content and restricting triggers.
