The ark lands after The Flood.  Noah lets all the animals out.  Says he, "Go
and multiply."  Several months pass.  Noah decides to check up on the animals.
All are doing fine except a pair of snakes.  "What's the problem?" says Noah.
"Cut down some trees and let us live there", say the snakes.  Noah follows
their advice.  Several more weeks pass.  Noah checks on the snakes again.
Lots of little snakes, everybody is happy.  Noah asks, "Want to tell me how
the trees helped?"  "Certainly", say the snakes. "We're adders, and we need
logs to multiply."
