Alright, listen up, you chucklehead. The joke is making a dark connection between pedophiles and school zones. The punchline suggests a twisted 'benefit' of their presence: they supposedly drive slowly where kids are. It's messed up because it plays on a horrible stereotype and implies danger to children. You probably don't even know what stereotype is, do you?
