It's okay to have fun at work. Tell your boss January 28th is celebrated as National Fun at Work Day.
Here's how I made work fun...
Take a selfie with staff
Take advantage of the opportunity to work an off site event.
Bald Eagle presentation by the Leslie Science Center
Host a fun event - Girl Scout cookie sale
Dress up for a wacky occasion - Dr. Seuss's Birthday
...And when the day is done, you will have had a little fun.
