Brady has been holiday - but the Yahtzee videos continue.

See all our Yahtzee videos in one playlist: http://www.youtube.com/playlist?list=PL8D3EA4DDD533BEE5

Filmed at Constance Moofushi, in the Maldives. Special thanks to the guys at the Blue Tribe Diving Centre for loaning me their underwater GoPro housing.
