In 7th grade summer camp our teacher had us do a survey of the neighboring village in teams, by just walking up and asking people questions like "what's your job?" or "what is the quality of running water in the village?".
The third or so person we interviewed was a man smoking on his balcony, who told us he was a professional smuggler, he has never gone to school, there was no running water in the village so they all have to drink alcohol all the time, and there was no school anywhere nearby, but that's okay because the local bar can teach children everything they need to know: to drink and brawl. And then he told us to send any other survey teams his way, because he'd be more than happy to help us out.
