My parents had me convinced (and I still cant do it) that if you ran the vacuume over the cord, you would die. And they told me that the yellow lines in the middle of the road are where runaway kids have to walk. Also, the "watch for falling rocks" signs meant that you had to watch for a little runaway indian boy named Falling Rocks.
