A polar bear swims in the ocean, searching for food.
He swims past a group of icebergs.
"Wait a minute, those icebergs remind me of me in some way," the polar bear thinks to himself.
"What could it be?" he wonders.
Then it hits him.
The polar bear and the icebergs are both made of frozen water!
The polar bear laughs to himself, "This is really funny!"
