The first Mortal Kombat prank that had people cowering in fear of Sub-Zero racked up an incredible 27 million views on YouTube. Which of course meant that prankster fouseyTube would be back to freak out unsuspecting riders foolish enough to step into his elevator. Only this time he's taken the form of lightning god Raiden. 

Most of the prank victims get a good laugh out of the gag, but that first guy, I think he might still be cowering in a corner somewhere.
