Phenomenal Mistake

I was recently informed that a paper I will not name out of professional courtesy (wink wink) in a town I will not name either (but it's a small town known for mushrooms) mentioned in a sports story that a young swimmer turned in a good performance despite her recent recovery from a bout of what the paper called "double phenomena."

Now, there are mistakes born of pressure, or of bad judgment, or mistakes that come about simply because a certain percentage of what you do will be wrong just because. But obviously what we have here is a mistake of sheer ignorance. You only have two lungs, and "phenomena" is the plural of "phenomenon," so the phrase "double phenomena" is clearly redundant. I mean, sheesh!
