The lyrics of the song warn you, "The magnets ruin my radio, but with my Plastic Jesus I'll go far!"
I long for the days of sheet metal dashboards and no safety glass. Detroit knew how to build cars then. Between them and Big Pharma cranking out quaaludes, aka, "Car Wreck Pills", it really thinned the idiots out of the herd.
Not to worry though, if you'd got your butt to church, Jesus had drop-kicked you through the Goalpost's of Life. You knew you were covered when you went flying out the front windshield in those seat belt's optional day's.
