"The human birth rate is two females for every male," read the man off his laptop screen. "Oh, my."
"How is that even possible?" asked Amy.
The man shrugged. "Seems normal to me. Or maybe it doesn't. I've been in so many different universes, I've lost track."
"So how do you get from universe to universe?" Amy prodded.
"You wouldn't like it." The man shook his head. "You're not magically charged in the way I am. You'd end up somewhere random, and might not be able to get back. Somewhere worse than this."
Amy indicated the skimpy outfit that didn't cover much of her body. "How much worse could it be?"
"Could be a world where there was a nuclear war last Tuesday. Could be a world where hostile aliens have invaded Earth. Could be a world where George W. Bush had become president instead of Al Gore. It'd be hard to tell, and you probably wouldn't be able to get back."
"But if it really is random," suggested Amy, "who's to say it won't be a world where I'm a millionaire supermodel-slash-actress?"
"I suppose," said the man. "Although you could have stated that while you were standing in front of the parallel universe window --"
Lina chimed in. "Hey, I want to be a millionaire supermodel-slash-actress!"
The man started, "Well, the problem is --"
Lina picked up a wooden stick from a bin near the counter. "Hey, is this an actual magic wand? I wish I was a millionaire supermodel-slash-actress!"
"Don't wave it!" yelled the man. But it was too late.
