There's gotta be a logical explanation for this.

Entertainer and possible sorcerer Rick Lax has made this video in which he attempts to guess a shape you're thinking of based on a number you've chosen and whether you're a man or a woman.

There are several small steps involved and some simple math is required, but there's nothing here that should make it too hard for you to do. It only take about two minutes and the ending may leave you speechless. Or, angry, if he guesses correctly and you're at a total loss for how he did it.

So, did he guess your shape? If yes, you're going to want to try again to see if it was just a fluke. If no, well, you're going to want to try again to see if he's as much a hack as you think he is. Either way, admit it -- it doesn't matter if you're a man or a woman because we can predict this trick has captivated you.
