I was aware of Gangnam style before my teenage foster kids, so we had a good laugh in our house with me teaching them the dance in my living room. The kids joined in and thought it was HILARIOUS.
We went to watch a Halloween parade on Sat night, a float stopped along side us with dancers doing the dance.
So I joined in and was dancing on the sidewalk - suddenly this was NOT hilarious for the kids and they wanted to die.
I am a firm believer that teenagers should be horribly embarrassed by their parent figure.
