it looks delicious #1

The observer, while eating something from his hand, is standing some feet away from a large adult cockroach and they are facing each other. They are both about the same size, but which was made smaller or larger is unknown.

Then the observer drops a few bits of his food onto the floor.

Then the cockroach's antennae suddenly drops to the floor, and he says; "Are you going to eat that? It looks delicious."

And the observer says; "I thought you couldn't see anything, how do you know it's anything good to eat?"

And the cockroach replies; "To a cockroach, everything looks delicious."
