Anytime "Killing in the Name" comes up, I have to tell the story of the time I was bringing my oldest to his second week of kindergarten and he requested this song, which was his favorite at the time.
I realized I may have created a problem for his teachers when he started shouting along with Zack "FUCK YOU, I WON'T DO WHAT YOU TELL ME!" We had have a little talk about not using adult words at school and how his kindergarten teacher really wasn't the problem with the system.
His second grade teacher, though... My son's anti-authoritarian ~~steak~~ streak served him well, there.
