The Ark

Noah brought the animals on to the ark in pairs.
And after days of rain, the ark reached land and Noah let the animals back out.
Then, when the checklist was complete, he watched a brood of platypus chicks crawl down the plank.
Noah called the beavers and ducks over for a meeting.
“We were bored!” cried the beavers. “It was dark in that boat. Things got confused.”
“We were drunk!” growled the duck. “They took advantage of us!”
Noah sighed, dismissed the animals, and looked at a horse.
“I don’t want no centaur-babies,” said Noah. “You’re having an abortion.”
