McDonald's Canada celebrated the return of its decades-old Monopoly promotion recently by accepting Monopoly money as legal currency at its restaurants. Check out the video below for footage. Unfortunately, they didn't honor the money at its face value—a $100 bill got you a single free large fries rather than several dozen. Still, a fun idea from ad agency Cossette, which has been doing some other interesting McDonald's work of late—including the giant cup-lid umbrellas for the beach, and the sly nappers planted under subway ads for coffee.
