Note: It was supposed to be slash, but that didn't really work. So I thought, why not? My very fisrt Sheldon/Penny (thought I'm more of a friendshipper for them myself).

Note2: all info on laughter came from wikipedia, obviously. I can't even type those big words all by myself.

He did it again and Penny couldn't repress herself anymore. "Ok, I've been delaying this question way to long. What the heck is that?"

"What?"

"That thing you do with your mouth."

"Talk?"

"No, the choke thingy."

Since he still looked confused, she demonstrated, taking short breaths of air and coughing it out. "You know."

"Oh" he smiled. "That is laughter."

"Laughter?"

"You made a joke and I laughed."

She stared at him. "Where do I begin? Well, laughter is a vocal way to express happiness or amusement-"

"Sheldon, I know what laughter is!"

"There you go."

"But that is not laughter" she said, chuckling herself.

"Of course it is."

"Nooo, it is not."

"Yes, it is!"

"If you're dying, maybe."

"I'm sorry, do you think you know more about this subject than I do?"

"Uhn, yeah. Clearly."

"Really?" He put down his cup and stepped closer. "Did you know that laughter is linked with the activation of the ventromedial prefrontal cortex, which produces endorphins after a rewarding activity? Did you know laughter can lower blood pressure? And strength cardiovascular functions? And reduce stress? Did you know laughter can help the human immune function by raising levels of infection-fighting T-cells, disease-fighting proteins called Gammainterferon and B-cells, which produce disease-destroying antibodies? Did you know that?"

She took it all in for a few seconds. Then said, "Did you know that laughter actually sounds like this..." And gave him a demonstration. It sounded musical and honestly joyful.

Sheldon was unimpressed. "Oh, score." And rolled up his eyes and headed to the sopha, turning his back on Penny.

Huge mistake.

The next thing he knew, he was on the couch, twitching and screaming as she tackled her sides and ribs and stomach and everywhere she could reach. Sheldon was breathless and in the back of his mind he worried about suphocating, but that only lasted until he burst loudly into incoherent breathing and wide smiles. "Stop's" and "don't's" and "get off me's" tried to make it out of his mouth but could only be stammered and soon forgotten. That was a mess of madness and Penny kept on going, taking control over the muscleless body pretty easily. When she managed to sneak into his armpits, though, he jumped up in reflex.

Penny's hands dropped and Sheldon stopped laughing. It took a while for the both of them to understand what was happening. Sheldon had jumped right into her lips. And Penny hadn't move away yet - though, he had to admit, she wasn't encouraging him much either.

When the shock worn off, they parted and she stared into his eyes, trying to figure out what had just happenned.

Sheldon waited for his breath to go back to normal, before saying, "I know this is probably bad timing, but... you're in my spot."
