Out of the blue, Louis's parents ask for tips on being cool. At first Louis is amused and teaches his parents how to use words like 'safe,' 'wicked' and 'sick,' and how to touch fists. But then Louis's dad turns up outside his school dressed like a rapper, yelling, ?Yo everyone, I'm looking for my blood. Is he here??

Soon his parents are trying to 'friend' Louis on Facebook and then Louis's dad is seen wearing a baseball cap round the wrong way. It's time for Louis to take action - and fast. The fantastic sequel to the best-selling How to Train Your Parents.
