It was a quiet day on the Ark and Noah was getting bored, so he told his wife that he was going to relieve the tedium by going off on a fishing expedition. "That's a good idea," she said. "You could do with a break." Noah collected all his equipment and set off, but thirty minutes later he was back and still complaining that he was bored. His wife said: "I didn't expect you back so soon. If you're that bored, why did you stop fishing after only half an hour?" Noah said: "I only had two worms." What's the difference between a fish and a mountain goat? One mucks about in fountains . . .
