Ah yes, Klein bottles. When I was a child, I was assigned to Escher Elementary. It had a great math program, though I did have to walk uphill both to and from school. Then I graduated and was assigned to Klein Bottle Middle School. It had a good reputation, but I could never find the front door. I had to transfer to Hyperspace Tech, which fortunately has a front door everywhere.
