Um, people, let's get off our high-horses here - we're not talking about Sex Education; we're talking about dirty songs. If you want to teach them to your kids and discuss them and have your kids singing them in public, that's your business I guess, but the self-righteous condescension is a little irksome. Personally, I wouldn't want to deny my kids the sinful pleasure of learning them from some greasy hood in the schoolyard and imagining how shocked the strait-laced adults of the world would be if they only knew. Actually, my own kids are grown-up now; they somehow made it into fairly-healthy adulthood without ever hearing dear old dad sing about the cabin boy who "put pieces of glass inside his ass to circumcise the skipper". And they'll have to struggle into old age bereft of the benefit of that experience, I'm afraid.
