1. Airplanes would go really fast off of ramps
    I used to think that airplanes worked by driving really fast on the runway and then going off a ramp and landing wherever you wanted to go.
  2. Giraffes and Elephants lived in the U.S.
    One day when I was riding in the car, I said, "You never see any giraffes in the wild here."
  3. There was a big bridge across the ocean
    When people referred to the other side of the world, it made me think that there was a big bridge that connected the two "sides" of the world. Oddly enough though I always pictured it as a walking bridge. That would be a long walk!
