Depending on how you fare, you'll think this guy is ether a genius or an attention seeker with no substance who can't back up what he says (and, no, we're not talking about Donald Trump).

Lasse Balama has turned the internet on its ear with this Facebook video in which he claims he can guess the number you're thinking.

The clip is short and pretty simple: all you have to do is answer a few simple math questions and then at the end of the video he guesses the number you're thinking.

It's an old-time magic trick in a 21st century tech arena.

Yes, Balama got some right, but Britain's Mirror estimates he only guessed correctly about 1.5% of the time, which is no great shakes.

And because this is all happening online, people are not shy about expressing themselves when he's wrong. Which is why you don't need to be some sort of Jedi to guess that people are going to post snarky comments online. It's just the way the world is.

So, what do you think? Is this guy legit or is this nothing special whatsoever?
