My kids are obsessed with poop.  We moved to Alaska at the start of the “snow season” and during spring breakup, we discovered that the neighborhood moose had crapped all over our lawn.  As the boys and I were wandering around the yard one day, the mighty sport of Turd Hunting was born.  Basically, it is a great game, where I can sit on my ass and read while they scout out the yard for poop.  When they find poop, they have to yell, “TURD!”  It entertains them for hours.  But they are simple kids.
