After Noah died he went to his place in the Kingdom where he stayed for centuries. But he started getting very bored so he decided he would like to return to Earth. So God sent him down. He grew up and, because of his natural sailing skills, he became a sailor.
He is sitting in a pub telling drunken stories about the ark one day, a crowd gathered listening intently:-
"So there we were, water everywhere. And the bloody animals were all over the place, stinking it out. There were piles of shit everywhere. As fast as we were shovelling was as fast as it was building up. Tons of it. And after 38 days and 38 nights I could bear it no longer. I got everyone and everything that could use a shovel and we started throwing it over the side. We shovelled and shovelled and shovelled."
"Where abouts was this." someone piped up from the rear.
"I believe Columbus found it a few years later."
