With facepalm every time you load your control panel you'll be greeted by an epic dad joke on the dashboard.
One thing that I think people really don't understand is that fun ? unprofessional. We aren't robots. We're people with feelings and emotions and sometimes we need to laugh.
Sometimes that chuckle determines whether your work day is fun or blah. As I've always said, "a dad joke a day keeps the sadness away".
