I said that the cock and the glass are homeomorphic.

Nippon is like that. A glass of homeomorphic cubes, balls and so on. And the cock has a hole through the mouth to the poop. He is homeomorphic touru and circle. And this is only if the respiratory system does not connect with the digestive as in mammals. This is when we drink water and it can get into the trachea. In this case, the cock is even more difficult.
