I'm old enough to remember perennial joke candidate Pat Paulsen. Pretty sure I remember some elections where he another write-in candidates showed up. Of course there needs to be a certain minimum to be listed. And you probably have to look pretty hard, it certainly won't show up in USA Today or whatever. Maybe only some official stats buried on each state website or state records or whatever.

I also worked as an election judge in Wyoming, which is what they call polling place workers. We were not allowed to throw away any ballots. Those are all recorded somewhere.
