So all the animals file two by two off the Ark, and Noah tells them to go forth and multiply. Almost all the animals shuffle/stampede/slither/fly away, but a pair of snakes stays behind.
Noah comes to them and says, "Did you not hear? Go forth and multiply!"
One of the snakes says, "But... we cannot multiply."
The other snake says, "We are adders."
Noah replies, "Ah, I can help you." He goes into a nearby forest and returns with some dead and incredibly wet logs. Then over the course of a day, he fashions the logs into a crude table, complete with benches. Finally he takes the two adders and places them on the table.
"What shall we do now?" asks one of the snakes.
Noah says happily, "On a log table, even adders can multiply!"
