Its’s important to keep a professional head on your shoulders if ever you find yourself on a photo shoot with an extremely attractive model.

But in a video prank, Weberz Way Films & Filmblock Productions decided to see how everyone would react if one of the production crew started to act a little strange around all the gorgeous women.

He ended up getting all the attention. Why? Because he was equipped with a massive fake boner!

That’s right: a rogue stiffy. He starts off in the background in a green-suit with a light reflector held around waist height, but as the shoot commences, he lifts it up and reveals the embarrassing bulge.

At first the models don’t notice what is going on, but as they are instructed to do different poses they spot the … thing. Of course it was all fake – but that didn’t stop the women collapsing with laughter.

It might seem a bit of a creepy stunt – but it’s become a huge talking point and a big hit on YouTube, notching up nearly four million plays over the last week.
