Having a Mohawk was really cool. At first I felt silly, but after a couple days, I got quite used to it and actually embraced it. I liked being the "Mohawk Guy."
But how great is a workplace when it is encouraged to come in dressed for Halloween. Folks have been known to wear shirts with dirty words on them, or shorts in the cold of winter, and shoes are entirely optional. Some of my co-workers have even dyed their hair "crazy colors" like blue.
Normally blue is not a crazy color, like salmon, but when referring to hair, I think this qualifier is on the money.
