"There are the those who say that every possible thing always happens and we just experience one possibility, although an almost infinite and ever increasing number of other versions of us experience all the alternatives."
"I know. So they'd say that in some version of reality everyone in my street has just run naked from their doors screaming 'Yumple is a Bumbler'?"
"Some professional quantum physicists would say so."
"And in another version of reality the naked ones are screaming 'Yumple is a Bop'?"
"Serious thinkers do say so, although not in such specific terms..."
"And in other versions of reality the naked nutter neighbours are all saying each of these things but with saucepans on their heads, while at the very same instant in Italy the Pope has just stood up and said 'Stuff this for a game of soldiers I'm going to become a drag queen,' while hopping on his left leg, oh, but on his right leg in yet another version of, eh... reality?"
"They are not joking, these quantum theorists, you know."
"And in another..."
"Yes, yes, I get the idea."
"It's nonsense isn't it?"
"Some clever people would not say so. Professor people."
"Some clever people are mad."
"Perhaps, but in some versions of reality they are considered sane."
