Joke of the week

One day, in Bible land, long after the great flood waters had died down, God calls down to Noah and says, "Noah, I want you to make me a new Ark".
Noah replies, "No problems God, anything you want, after all - you're the boss...
" But God interrupts, "Ah, but there's a catch. This time Noah, I want not just a couple of decks, . . I want 20 decks one on top of the other".
"20 DECKS!", screams Noah. "Well, OK, whatever you say. Should I fill it up with all the animals just like last time?"
"Yep, that's right, well . .. sort of right . . this time I want you to fill it up with fish", God answers.
"Fish?", queries Noah
God replies; "Yep, fish . . well, to make it more specific Noah, I want Koi carp - wall to wall, floor to ceiling - Koi Carp!"
Noah looks to the skies. "OK... let me get this right, you want a New Ark?"
Yep...".
"With 20 decks, one on top of the other?".
"Right".
"And you want it full of Carp?".
"Yes"
"Why?" asks the perplexed Noah, who was slowly getting increasingly worried about either the sanity of God or his own hearing...
"Dunno", says God...
"I just fancied a Multi-Story Carp Ark".
