Then cream goes on top, and in the cream there is a shoe with a rhino logo, which looks odd: cream (Sahne in German), shoe, rhino and odd give you sa šunkom. A hedgehog jumps out of it and walks off to Rome, singing – hedgehog (Igel in German) and Rome give you i sirom. And how does it get to Rome? In the morning, in the limousine with the vase: molim vas.
The most effective way to retain a sentence like this is to tell somebody else about it. Find a victim in your family – in most cases they end up wanting to learn it too.
