With the Ark settled safely after the flood, Noah opens the doors and commands the animals, “Go forth and multiply!” 

All the animals depart the Ark, except for two snakes in the back. 

Noah proclaims again, “Go forth and multiply,” yet the snakes stay put. 

Perturbed, Noah finally asks them, “Why have you not followed my command?” 

The snakes flicker their tongues and answer, “We can’t multiply, Noah—we’re Adders.”
