Why Do People Stick Out Their Tongues?

Why do grown adults stick out their tongues for pictures?  Do they know how disgusting the tongue is?  Don't get me wrong, the tongue serves many purposes.  But it's not pretty.  If you think about it, it's like a very short, very fat snake attached to the inside of your mouth.  It's best to keep it hidden inside your mouth out of sight to do it's job.  I think people think that it makes them look like they are having a wild and crazy time so when the cameras are rolling, the tongues start coming out.  Trust me, having your tongue hanging out during a picture does not enhance the picture.  Leave it in.
