Ryan Reynolds reveals some highly questionable parenting strategies from the animal kingdom's worst parents, the underdogs. From a goose who lays their eggs on the top of a cliff to a koala that feeds its baby poop, it's uncertain if they are bad parents or just misunderstood. But no matter how bad you think you may be at parenting, you can't be as bad as these guys.

Forget the birds and the bees, Ryan reveals the steps to finding "the one," underdog-style. From the "first attraction" in giant-nosed proboscis monkeys to the importance of wingmen in turkey courtship to foreplay in flying foxes, these guys have re-written the rule book on messy and complicated relationships.

Ryan Reynolds puts the spotlight on the underdogs who get ahead by sneaky tactics. From the master-of-disguise frogfish to a butt-biting jackal and a multi-headed caterpillar playing the decoy, these are the masters of deception and deceit. And bringing all these hustlers together is the greatest con artist of them all—a cunning macaque who feeds on the spoils from unsuspecting tourists.
