Noah opens up the ark and let all the animals out, announcing to them all to follow God’s command and “Go forth, be fruitful and multiply.”
He’s about to close the great doors of the ark when he notices that there are two snakes sitting in a dark corner and not making a move to leave. So he says to them, “Didn’t you hear me? You can go now. Go forth and multiply.”
The snakes reply, “That command doesn’t apply to us.”
Noah shakes his head and asks why.
“We don’t,” said the snakes, “we’re adders.”
