This one is just for laughs. Yall've seen it before, I always seem to make this fish and this bird fall in love. I just don't know why, but they look like the'd like each other.
Oh and the answer is the fish's place. I figure they could stay in shallow water where the bird could stick his beak up, because the fish would definately die in a bird nest, but a bird could maybe live with a fish. You can choose one of two mental images:
1. water thrashing about with just the bird's beak sticking up. (this is the naughty version, they are... um... occupied under there.)
2. The bird back floating all beautiful in the water with the fish swimming around it.
