There's only one country in this world. You would think that would be a recipe for peace. But haven't you ever heard of civil war?

No matter how much people try to stay united, some people will insist on being divided. It's just human nature. We don't conform. We rebel. So instead of focusing on similarities, some people have to classify themselves based on their differences.

That was the premise behind the first meeting of the PBS (Proud Bald Society). The members of the fledgling group filled the park, their heads shining in the mid-morning sun. Romulus Jones, their president, addressed them on the microphone.

"No longer will be cover our heads in shame!" he intoned. "Hats and head coverings of any kind are banned! Rogaine is an illegal drug! We are a big-tent society, so we are not limited to old men who are going bald. Encourage your friends to join us!"

The crowd cheered.

"And one more thing ... we need women!"

The crowd cheered louder.
