I am a very big 80's fan, so when the song "1985" came out by Bowling for Soup I was happy! BUT the part that goes "She was gonna shake her A** on the hood of whitesnake's car..." I totally misheard... I love whitesnake and now know that the real version is much better than "She was gonna shake her a** on the hood of my 6th car..."
