Robin Williams is no stranger to promoting Nintendo's Zelda franchise. He named his daughter Zelda, so it's safe to say he's a fan. Now he's back in a TV spot for Nintendo's free download of The Legend of Zelda: Four Swords Anniversary Edition. Watch Williams lose a beard-based bet below!
Commercial or not, you can see his genuine adoration for the series in both the adverts in which he and his daughter are featured.
As we mentioned before, Four Swords Anniversary Edition is available as a free download for a limited time—through February 20, 2012—via the 3DS eShop and DSiWare.
