1. Get a camera.
2. Get an animal.
3. Wait for a tongue to stick out.
4. Get a snapshot.
5. Post such pictures to a Website called, say, "Animals With Their Tongues Sticking Out."
6. Look at all the pictures of animals with their tongues sticking out.
7. Rejoice.
8. Resist becoming one of the animals with their tongues sticking out your own darn self.
