When the animals came off the Ark, Noah told them all "Go forth and multiply."
To the Lions, "Go forth and multiply." and they said, "Yes, Sir!"
To the dogs, "Go forth and multiply." and they said, "Yes, Sir!"
To the snakes, "Go forth and multiply." and they said, "Sorry, Sir, we are Adders!"
Then Noah said, "Go over by that wood pile and wait while I dismiss the other animals.
Then Noah said to the foxes, "Go forth and multiply." and they said, "Yes, Sir!"
To the horses, "Go forth and multiply." and they said, "Yes, Sir!"
When he was finished, Noah went over to the wood pile and was surprised to see a lot of baby snakes slithering around.
"I thought you said you could not multiply."
The snakes replied, "Oh, we Adders can multilply by logs."
