The Genie's Dilemma

Abu-Hassan; a gigantic, green skinned genie sat somewhere near to the end of infinity trying to work out a problem.
Two thousand years ago a fisherman had released him from a bottle and he had just been about to shrink the fisherman to the size of a bobblehead when he had made the mistake of going into a speech about how amazingly powerful he was.
"I am Abu-Hassan, greatest genie in all the universe; there is nothing beyond my power", he'd been saying in his booming thunder and crashing lightning voice.
Ofcourse then the fisherman had interrupted him.
"Nothing", he'd said, "I can think of something beyond your power".
"What?", he'd said, grinning overconfidently.
"I bet that you can't put every box in the world into a box", the fisherman had replied.
Ofcourse, he'd always been a sucker for a bet and it had sounded so easy, atleast for someone with his powers so he'd agreed to try the fishermans challenge.
Unfortunately, he'd realised too late that what the Fisherman had asked him to do was impossible.
You see, once he'd put every box in the world into one box then he'd had to put that box, because it was a box in the world, into a box and then he'd had to put that box into a box.
In short, he'd been putting boxes into boxes into boxes for almost forever.
Ofcourse, he could have simply swallowed his pride, gone back to the year 4 A.D. and admitted to the fisherman that he'd lost the bet but that was a hard thing for a genie like him to do, almost as hard as infinite boxing.
Still, how could it be done? There never could be a final box.
Angrilly, he crushed a box the size of a football stadium in his right hand.
Just then however, he looked down at the crushed box and, seeing its edges folded over into itself, suddenly it was as if the little genie inside his head had turned on a light.
"Why its so simple", he said, picking up the box again and, looking at it, bellowing with laughter like a barrel of thunder.
All he had to do was fold the walls of the final box over so that the box was partly inside itself.
He clicked his green fingers and suddenly he was in the deserts of Arabia again, 4 A.D., a startled fisherman at his feet.
"Mission accomplished", he said to the fisherman, "Now where was I? Oh yes.  I am Abu-Hassan, greatest genie in all the universe...".
