I actually heard it the first time in my US history class junior year. We had a student teacher at the time, it was probably part of why the regular teacher got her fired. Which was too bad cause she owned and was way better at her job than he was.
I was kind of joking. Every school year where we would learn about the Cold War, a teacher would play that song and then say how it completely missed the important parts of that era.
Crack was actually part of a communist plot to bring us down from the inside. Too bad the failed to account for our utter disregard for poor people and black people. Also black people who are poor. Stupid commies.
