When I was a kid, I worked in a furniture store. One day, we were coming back from a delivery and was stuck in traffic/red light. Older guy driving said "hey - you want me to make that guy dance?" He pointed to this older dignified black man sitting outside eating. He looked well educated and had white mannerisims if you know what I mean. Not a ghetto bone in his body. My co-worker found a black radio station and blasted the music. The old man suddenly started dancing. It's like he didn't know he was doing it; just nature took over. Co-worker says "they can't help it". We did this again on other deliveries with the same results no matter age or gender.
