Why is the why did the chicken cross the road joke funny?

The joke itself is not really funny at all. It's the result of the joke that is funny. People who have not heard the joke will become victimized by their own intelligence. They will sit there and try to deduce why a chicken would cross a road, coming up with outlandish and foolish answers, when the obvious answer is staring them right in the face. Why does anyone or anything cross a road? To get to the other side. Children will usually answer correctly the first time asked. Adults will not. Thats why it is funny.
