I read about this once...some future-past, past-present-old thing from this scifi book. Sort of a "mythos" deal. Something about a quantato? I don't know. Quote is from a book report on the deal I wrote as a kid.
And then the man used a machine. It made the potato angry, which hurt the bad men and the machine was caled (sic) a "penultimator". I don't think it was good though.
