When I was really young, my older brother told me it was illegal to write on the left side of the margin on paper...and so in grade one, when my teacher told us to number our paper by putting numbers in the left margin, I yelled out to the class, "No, don't do it! You'll get arrested!"
Of course, they all laughed at me...but I still believed it.
