The button text is a playful adaptation from the 1999 comedy film Office Space, where the boss, Bill Lumbergh, tells his employees that Friday will be Hawaiian shirt day:
"Oh, and remember: next Friday... is Hawaiian shirt day. So, you know, if you want to, go ahead and wear a Hawaiian shirt and jeans."
