Comedian and viral sensation Grégory Guillotin’s hilarious video of him pranking male shoppers has almost racked up five million views!

In case you haven’t seen it yet, the naughty Frenchman was filmed on YouTube channel Nou, caressing dudes’ hands as he passed them on the escalator – and the reactions of his victims are priceless!

The guys get even more wound up when Grégory continues the flirting by giving them a cheeky wave or blowing a kiss.

Our favorite has got to be the old dude whose eyes almost pop out his head! As he walks off he gives the joker a gesture… we’re not sure what it meant but we can only imagine it means ‘f*** off’ in French.

Relax guys, it’s not like Grégory was reaching for anyone’s nuts!
