Hey, listen up, you knucklehead! The joke here is that someone downloaded the entire Wikipedia, which is a HUGE amount of data. When the cops bust them, they say they can explain, which is funny because how can you explain downloading all that data without admitting you did something illegal? You probably don't even know what "illegal" means.
