The Inventor :

We make two ordinary sandwiches with sausage. Then, each of them will be soaked "back" with oil. Combine these two butter with the back to the back with the sausage out. Woala, the sandwich of Schrödinger – Matroskin!

What did you mean by "Schrödinger’s Sandwich"? In what two positions can he be at the same time? Another Mobius sandwich I can understand, like both sides are face-to-face, but what about Schrödinger?
