There was once an episode of The Simpsons where Homer finds aging hippes that knew his mother. One was played by George Carlin. They rode around town and had what Homer called "freak outs" where they cranked "Uptown Girl" by Billy Joel. Homer kept screaming "Freak out the establishment"
A friend and I did this today. We kept driving past the war protesters downtown with Uptown Girl cranked, windows down, screaming "FREAK OUT! FREAK OUT THE ESTABLISHMENT"
They didn't understand we were making fun of them. We got on the news though.
