You're allowed to be Hitler, but don't even try being Gay on social networking site Facebook. It's been revealed that the popular website -- which boasts it has over 30 million members from around the world -- does not allow people with the common surname Gay to join, assuming it is not a legitimate name. In a test of using the last name Gay, the website would not allow the new member to join. "Please enter a legitimate name,'' the website stated during our attempt. And while the website refused Gay, it had no problem allowing us to join with the last name Hitler.
