Prankster Jack Vale and his crew may have come up with their most evil prank yet. Just as excited moviegoers were exiting the premiere of the new film 42, Jack and his friends would raise their hand and yell ‘high five’ to passersby. 

It’s almost instinctual to slap a person five, even when the one requesting the slap is a complete stranger.  

But as is evident from this prank, people must be cautious of who they high five. They may just have vaseline on their hand, ready to ruin your day.
