Why you should not use your mouth before engaging your brain

Scene: my wife and I are sitting at our respective desks in the study, doing our respective things on our respective computing systems.
Her: “Wow. There are thirteen miners trapped in a mine in West Virginia.”
Me: “What the hell are a bunch of minors doing…”
That was the point I shut up and then started laughing. Then I had to explain the insanity that took place in my mind, to which my smiling bride stated, “Doofus.”
Doofus, indeed.
