Watching those vids reminded me of the old elementary and middle school B/W WWII films on the projector. You know... The one's where the Nazi's would barge into people's homes to do the "house checks". If I remember correctly, those old B/W films were to teach us about our nation's freedoms. Scary world we live in now.
And my parents thought the worst thing I would ever have to endure in life was hearing damage from listing to AC/DC, Def Leppard and KISS.
