You REALLY know your old when you're driving in the SUV with your family and the wife changes the channel to the Oldies Station and you hear Metallica and Iron Maiden and you ask her to leave it on there...
The kids "What is that Sound"
Mom "This is what Daddy used to listen to when he went to the Mosh Pit"
The kids "what's a Mosh Pit"
Me "Just change the freakin station"
