"What the hell Sheldon?" George Cooper barked across the room at his brother.

"There's no need to curse George. I'm simply fixing this equation." Sheldon got it out as fast as he could.

"There's absolutely nothing wrong with that equation…and you know it." George had missed being around his brother, but as ever was infuriated at how difficult he could be.

"I know that." Sheldon said it so flatly that it was more a declaration of the mundane that a defense of what he had done. "Your hand writing is still atrocious."

The two brothers had gone back to working oblivious of the fact that the back three rows of the lecture hall were filled with people just wanting to watch them work. Not just students or grad assistants either. More than couple professors from various departments had "just happen to be walking by" and found their way in.

That's how Penny found the lecture hall when she entered, round fifty people in the back watching two men that were not paying them slightest bit of attention.

"You!" George pointed. "Tall kid in the green hoodie. Come here." George ordered nonchalantly.

The nervous, but yet excited under grad stood up and headed down the stairs. Sheldon quickly looked at some writing on the paper he was holding and looked at George.

If they want to watch they might as well help." George said as he took the lanky kid in the green hoodie by the shoulders and told him to stand still.

"Ok then…" was Sheldon's only retort. "You there." He pointed at a small girl that had been several seats over from the other student. "Would you mind coming down here?" The girl got up and sprinted down the stairs to Sheldon. He was about to take her by the shoulders and move her where he wanted her positioned but quickly thought better of it and instead simply pointed at a spot on the ground and said "here please".

"Wolowitz and Penny. Front and center please." George hollered out without looking their direction. Both came down the stairs.

"Penny can you grab your laptop and get Professor Belkin on Skype for me please." George almost always spoke to Penny with a professional tone. "Wolowitz, I need a boom box or loud speaker of some sort. Quick quick." Penny started getting out her laptop and Howard bolted off down the hall to who-knows-where as fast as his little legs would take him. Sheldon started to become a little apprehensive when he heard what his brother had requested from Penny and Howard. George was well known for being what Sheldon would call a "wild child". He would often grab people out of audiences and use props to give a visual representation of the theories he was discussing on stage. He had actually become a must see for the students at Oxford and the lecture halls would often be packed. Once George Cooper got going, it was all spectacle.

"George. Good to hear from you. What can I do for you?" the gentile man said on the screen of Penny's laptop. Dr. Howard Belkin was plump and full of character. An overweight Colonel Sanders at first glance, but yet the charm of a devil. "How are you as well Penny?" Belkin said without missing a beat. Penny liked that the people George often dealt with always treated her like she was in the room. Sometimes the guys in the apartment across the hall didn't.

"I'm doing well Professor Belkin. How are you?" Penny said smiling into the screen.

"Sweetie, now that I've seen you, well let's just say my day has gotten a whole mess better." Belkin said with as much southern charm as anyone could muster while throwing her a wink.

"Howard. I want to demonstrate something for you and get your feedback. Once the speaker gets here." George interrupted the southern gentleman's passing flirtations with his assistant. "It's going to be loud so Penny is emailing you a formula." George looked to Penny as Wolowitz came running back down the stairs. "Penny. If you please." Penny sent the email.

"Any particular song?" asked Wolowitz plugging his phone into the little red portable speak he had found.

"You can't always get what you want by the Stones please." George said walking back over to the kid in the green hoodie. "Stand absolutely still please." He said it flatly to the kids face. "Young lady stand right here and please put your right hand up." Both students were starting to become a little nervous at not know what they had signed up for.

"Ok. I'm looking at your formula and I think I see where this is heading." Belkin said. Penny for sure didn't know where it was going and from the looks of it neither did Sheldon. He just looked a little worried and a little embarrassed.

"Ready." Wolowitz announced.

"Sheldon. I want you to look at this and tell me what you see when we start. Leonard would you mind recording this on your phone please." George said this and everyone else noticed that Leonard, had in fact, entered the room.

"No problem." Leonard said, just happy to be involved.

George walked up to his brother, "Green hoodie is a supermassive black hole ok." Sheldon nodded. "This young lady is a gravitational wave, ok?" Sheldon nodded again and looked down at the formula, the same one Belkin had been emailed. "I want you to listen to the high and low pitch of the music and imagine the sound waves as neutrinos in Nth dimensional space, ok?"

What none of the people on the floor of the lecture had noticed has how many people had entered the room. Winkle and Kirpke had entered as well as Raj and most of the astrophysics department. Several people were tweeting and some were discreetly trying to take videos.

"Let's begin." George Cooper said point to Wolowitz. The sound of the boys' choir filled the lecture hall and George Cooper began to move in between the two undergrad students he and Sheldon had hijacked into their service. As Mick Jagger's voice came in George could be heard saying something to Sheldon and Dr. Belkin about gravitational lensing, but that wasn't what sparked Penny's interested. As soon as George said it both Sheldon and Belkin lit up like children on Christmas morning. Penny looked around the room and several of the other scientists' faces just looked star struck. George kept dancing around and waving his arms while the whole room came to terms with what he demonstrating. The music filled the lecture hall as George ordered Wolowitz to turn it up. More and more faces could be seen looking in from out in the hall and quite a group had gathered. Sheldon literally started jumping up and down and clapping, like he had got a new train set. The entire lecture hall was loud with applause. Belkin was clapping and laughing on the screen in front of Penny and it was then the whole room started cheering. Everyone that is except for Winkle.

"Brilliant!" shouted Belkin from the computer monitor. "How did you come up with it?"

"I didn't." George said to the computer screen. "Sheldon did. I just threw in my neutrino research from 2014. Sheldon had already done all the heavy lifting with the gravitational data he collected. But the idea is sound don't you think." George had motioned for Sheldon to join him and had even put his arm over Sheldon's shoulder, which clearly made Sheldon uncomfortable, but he tolerated it for the moment.

"Absolutely." Belkin was having to yell over all the noise from the crowd that had gathered behind the Cooper brothers. "Get this down on paper and let me know when you do. I'm coming to see you as soon as the calculations are constructed."

"Done and done. See you soon, Howard." George said as he closed the computer screen, "Sheldon, I'm taking you to dinner. We have a lot to talk about." George said straight into his brother's face. "No arguments, almost anywhere you want. Penny gather everyone up in our little group and call my wife and tell her where to meet us. I'm buying dinner." George pulled on Sheldon and they exited to the left side of the auditorium.

"That's physics bitches. Coopers out." George Cooper yelled as he exited the room waving one hand in the air.

"What just happened?" Penny asked Raj who had been standing next to her.

"I think Coop may have just proved that String Theory is the viable model over the loop quantum gravity model." Raj said just looking at the crowd of people still talking.

"Then what's wrong with Winkle?" Penny asked again to Raj. Winkle just sitting there with her face in her hands.

"Loop quantum gravity is what her grant is based on." Raj said with a smirk.

Penny smiled, took Raj by the arm and followed the Cooper brother's exit path and headed out to have dinner with her friends.
