"It's my Friday!" is a common phrase amongst Cast Members which represents the day before their day(s) off. Having said it myself many times, I couldn't help but buy this pin. Not only do I think it's great that Disney has acknowledged this "every man" cry in pin form, but they've included a spinner feature which lets you change the day of the week featured in the calendar.
It's the little things like these that make Disney such a unique company to be a part of.
