Slangin' "yola" teaches kids the metric system.
You learn about physics when you compute angles for a drive-by shooting.
You learn leadership skills and how to get ahead in business.
You learn graphic design and marketing when you're out 'tagging' your crew's name/logo.
You learn chemistry when cutting dope and making alcohol out of orange peels in jail.
I'm sure there are more, but so far it's about as educational as a public high school.
