Prankster Yousef of Fousey Tube donned a Sub Zero ninja costume from Mortabl Kombat and waited in an elevator. When an unlucky person entered the elevator a clip of the famous Mortal Kombat announcer would scream ‘Test your might’ or ‘Finish him!’

That’s when Yousef would attack. For pretend of course. His prank victims were not happy. But viewers are loving it as this new video already stands with over 7 million hits!
