Rookie Mistake - Taking The Bait

One of my favourites is that old joke where someone posted on Reddit (or somewhere) "Murphy's law states that the best way to get the right answer on the internet is not to ask a question; it's to post the wrong answer. What are some examples where you've applied this law?"

And the first response is "This is Cunningham's law and not Murphy's law. Murphy's law is 'Anything that can go wrong will go wrong.'"

Classic

This is truly one of the biggest challenges of our time.
