Disclaimer: I don't own either of these shows. If I did, there would be a lot less of Rachel and Finn singing, and more Kurt. And some Santana.

Also: All of the theories that Sheldon mentions is crap and I pulled it out of thin air.

The Broadway Sound Travel Collision

A Big Bang Theory/Glee Crossover.

"Leonard, come look at this," Sheldon said.

"I don't want to see my mother's PowerPoint on her reproductive schedule," Leonard said. Sheldon looked up.

"If I wanted you to look at that, I would've specified: Leonard, come look at your mother's PowerPoint on her reproductive schedule."

Leonard sighed, and came over to his laptop.

"What is it?"

"Well, I was researching the speed in which sound can carry over air particles if it is said louder, such as in singing, and I stumbled across this." He pointed to the screen, which had YouTube on it. The video was titled: "New Directions at Sectionals." A girl with brownish-blackish hair and an odd nose was belting out Don't Rain On My Parade.

"Who is that?" Leonard asked.

"Apparently her name is Rachel Berry. She's in this show choir, otherwise known as a Glee Club," Sheldon said.

"You've never heard of a glee club?" Leonard asked.

"No. My mother signed me up for Bible Study, not choir."

"Well, so?" Leonard sipped his coffee. "She's good."

"Good?" Sheldon looked bewildered. "She's screaming. I don't know how you could perceive that as 'good', but she would be good research for my studies."

"Wait…you're going to conduct a study on a singing high schooler?"

"That is correct."

"And where exactly do they live?"

"Lima, Ohio."

"So…"

Sheldon stood up. "Ohio or bust, as they say."
