Leonard leaned back in the oversized chair in his apartment. He watched Penny pace slowly in front of him, an audition script in her hand. She flipped her long, blonde hair out of her eyes. He was always a little in awe that she was his.

"Whatca reading?" Leonard asked, trying to peek over her shoulder.

"It's a script for a TV pilot," she said, showing him the cover. "I'm auditioning tomorrow." She handed him the script.

Leonard glanced at the cover, "Beyond Worlds: A Journey of Strings," he read, and opened the script.

"Yeah, I thought it had something to do with kites, but I haven't come to that part, yet."

Leonard read a few lines. "Penny, this is a sci-fi show. I think this episode is about string theory."

Penny nodded, "Yeah, but they haven't even talked about string yet, so I can't quite figure out my character."

"No Penny, this is about string theory, the concept that all particles can be represented as strings or string-loops. It's helped resolve some questions about what happened right after the Big Bang. If you think about the universe as a string, you can also think about other universes next to it, like a violin.

"Huh," said Penny, eyeing the script skeptically. "Well, that explains the lack of strings." She flopped onto the couch across from him. "I'm trying out for Luna LaMore, a communications officer who may or may not be a cyborg."

"Very cool!" said Leonard, reading a few more lines. "You know, some of what they are saying here isn't right. The science, I mean, it's not really correct."

Penny offered Leonard that sweetly sympathetic smile the guys in her life so often earned. "Oh, sweetie, I don't think TV shows care about that."

Leonard marveled at how that look never bothered him. He knew he talked on an all-nerd level, but she somehow made it seem endearing when he babbled science. He was contemplating how to nerd-down the idea of superstring theory when the front door opened. Leonard glanced up to see Bernadette and Howard entered the loft, right in the middle of an argument.

"Now Bernie, it's not that bad," said Howard.

"Oh yeah? You try fighting crime without pants!"

Leonard smiled. "Hi guys."

"Hi," said Howard distracted. "Bernie, that is way she is drawn."

"Humph!" answered Bernadette. "I still say it is sexist that Wonder Woman wears no pants. She doesn't even get tights!"

Howard rubbed Bernadette's back. "Hey, she gets awesome, red boots."

"Howard, they ALL have boots, and hers are the only ones in high heels!" Bernadette yelped.

"Now honey, how could Batman save Gotham in high heels?"

"I think George Clooney did that," Leonard piped in. Howard shrugged in agreement.

Bernadette continued. "I'm just sayin'. She doesn't get pants, nobody gets pants."

Howard smiled. "I'm not sure you'd like to see Aquaman in just a speedo. It would look like my uncle Philman at his water aerobics class."

Bernadette shuddered. "You guys ready for the movie?" she asked.

"Sure," said Penny, and rose to grab her jacket. "Oh, Howard, do you still have that Star Trek girl's costume you wore for Halloween a few years ago?"

"Yeah." At Bernadette's curious gaze, Howard cleared his throat. "I was supposed to go as Captain Kirk, and my data as Uhura, but she insisted on being Kirk."

Leonard didn't even try to hide his smile. "Ah, Alicia. Isn't she Alan now?"

Howard held two thumbs up. "Only one more operation to go!" He raised an eyebrow at Leonard. "You planning something special tonight?"

Leonard rolled his eyes. "Penny has an audition for a new sci-fi show. But I was going to make some notes. Some of the science is off." He handed Howard the script pages, and watched as his friend's eyes lit up.

"Hey! 'Beyond Worlds!' I didn't know they were casting for this." Howard looked at Penny. "I used to read the books by L.P. Marken when I was a kid. I can loan you some, if you like." Howard flipped through the pages. "I see what you mean. They are updating it for string theory, but this part referencing Maxwell's electromagnetic field isn't right."

"Yeah," added Leonard. "And the whole part about the waveform collapsing doesn't include how it is relative to the observer's state."

Penny looked at Bernadette. "Wonder how they missed that!" she muttered.

Leonard raised an eyebrow. "Look, we could just make some notes on the collapse that you could bring up in your audition."

Howard grabbed a pencil. "And we could add in the waveform collapse here." He began to scribble.

Penny looked at the script. "Sweetie, you changed, "Oh God, a black hole! Narfa!' to "Oh God, a primordial dark-energy star formed by fluctuations of space-time! Narfa!'

Leonard smiled. "See, much better!"

Bernadette looked at Penny. "What's 'Narfa'?"

Howard lifted his pencil and glanced at Bernadette. "It's a phrase they use to mean 'royally screwed."

Leonard could not be sure, but he thought he heard Penny mutter, "Somehow I can relate to the feeling."
