Gnocchi

Some chefs make gnocchi, but I know a chef who makes gnocchi do tricks.
Most of the time, he makes the gnocchi do the standard tricks: sit, roll over, and play dead. Even shake hands.
But one day, he tried to make the gnocchi make gnocchi.
That’s right. Little food-based self-replicating Von Neumann machines, multiplying like bacteria.
Gnocchi everywhere, making more gnocchi, which were making even more gnocchi.
If he hadn’t have run out of potato flour, the whole world would have been overrun with gnocchi.
Which would gave been a tragedy, because his gnocchi tastes awful. Even in sauce.
