The Flood is over and the ark has landed. Noah lets all the animals out and says, "Go forth and multiply."
A few months later, Noah decides to take a stroll and see how the animals are doing. Everywhere he looks he finds baby animals. Everyone is doing fine except for one pair of little snakes. "What's the problem?" says Noah.
