Remember Bert the Turtle?He’s about to make a comeback.In case you are too young to remember Bert, was all the rage through the 1950s with kids. He had a bigger following that Elmo and Barney ever thought of having.And thanks to North Korea, Bert’s favorite move may return to the classroom.Bert the Turtle promoted the quaint practice of “Duck and Cover” that every American school child throughout the 1950s and into the early 1960s did as part of an ongoing school routine.Bert starred in the Federal Civil Defense Association film produced in 1951 that was shown in classrooms across the country about the best line of action to possibly survive a nuclear attack. Students were told when they heard warning sirens go off or if they saw a massive blinding flash to duck under their desks, put their heads to the floor, and then use their hands tightly to clasp their heads.If you think this is bizarre you obviously haven’t lived through the Cuban missile crisis.Testing of a civil defense warning system for the expressed purpose of a nuclear attack is being revived.
