A contestant on Who Wants to Be a Millionaire? started off by bragging about how smart he was - but managed to screw things up on the first question, leaving without winning a single penny. You can take a look at this chilling cautionary tale below:
The contestant was called Brenton Andreasik and he came onto the show full of confidence, then decided to tell host Chris Harrison about his intellectual abilities.
"I remember watching Millionaire as a little kid with Regis [Philbin] hosting the show, and it was such a phenomenon," he said.
"Ten million people watching a show about smart people every night, celebrating being smart.
"I thought, 'You know what, maybe it's not so bad being smart, maybe it's not bad being a nerd, maybe it's cool to be smart,' and I followed that along the way and I just graduated from medical school."
Then the audience applauds and the game can begin.
After a brief introduction to how the game is played - as if someone of his elevated mental capacity wouldn't already know that? - they get stuck into the quiz.
There are 14 questions that must be answered if someone is to take home the full million, and the first few are usually pretty easy.
As our mate is about to find out, however, they're only easy if you know the answer.
The first question up for $500 was: "Snapping selfies in kitchens you can't afford and taking 'a meatball break' are two things that Buzzfeed says every twenty-something does on their first trip to where?"
The four possible answers are a) to Paris, b) to London, c) to Rome, and d) to Ikea.
Now, we all know the answer to that question, but - again - it's only easy if you know it.
Our hero said: "I think they do serve meatballs in Ikea. I don't think that's the right answer though.
"So, kitchens you can't afford, meatballs, sounds like it's got to be Rome to me.
"In fact, if I won a million dollars I would love to take a trip to Italy, I'm going to say Rome - final answer."
Well, you ain't winning a million bucks lad, because it was Ikea.
Duh!
Strangely enough, he took it remarkably well. There was a moment of devastation and he placed his head into his hands, but then managed to retain his composure and shake hands with Chris before leaving the stage.
There you have it though, folks. Don't get cocky, because it could come back to bite you on the a**e one day.
Or, it might even do that within a matter of seconds.
