My doughnuts are generally not continuously deformable to coffee cups.
I'd have to poke them with a stick to make that true, and that would
squirt jam everywhere.

Would topology have still been the field it is today if doughnuts had
not existed?

But when I was a child in England, doughnuts were amorphous lumps and
were definitely not ring-shaped and had no visible hole. It took me a
while before I understood what Americans writers were talking about when
they said "donut-shaped". I don't think I saw a toroidal doughnut until
I was in my twenties.

All topology textbooks would contain pictures of coffee cups.

Or topologically identical people?

In fact, it could be your doughnut.

I'd have to poke them with a stick to make that true, and that would
