I don't own these guys. But I've wanted to write a misunderstanding for awhile.
Penny paused outside of 4A. She didn't really want to interrupt their little party. Or rather get stuck attention their party. Star Trek trivial, old video games and science talk weren't her idea of fun. Going out to a club and dancing was. Which is right where she'll be once she get Sheldon to find her shoes for her. They were in order, they had their places, till he messed them all up by putting them in some insane order that he thought they should go in. She'd told him to stay out of her apartment and not to clean things, but since when did Sheldon do anything anyone else wanted?
So she took a deep breath and screamed at the top of her lungs, "HELP, SUPERMAN!"
Her scream would have been loud enough to hear even if they didn't have the music turned to a Sheldon acceptable level. The party hushed, not that it was much of a party. Just a bunch of the Physics professors mingling and Sheldon kicking ass at trivial.
Howard barely had time to ask, "Did Penny yell what I think she yelled?"
Before Sheldon shot out a, "Yes, that will be for me. Good lord, I hope she's not locked out of her apartment. I'd rather her not wish to sleep in my bed as some sort of turnabout is fair play." With that he strode quickly to the door.
"Hey Sheldon. How do you know she's calling for you?" Leonard's question gave pause to Sheldon's actions.
"Yeah, she could be calling anyone of us." Howard chimed in.
"You three do realize I interact with Penny outside of our group meals and occasional together? She's making reference to a previous encounter we had. As was I making reference to the same encounter where I slept in her bed. Now if you'll excuse me Lois Lane has been captured by Lex Luthor again."
Sheldon opened the apartment door to find Penny tapping her foot. "Yes Penny, how can I help you?"
"I need you in my bedroom right now." Penny yanked him by the collar back to her own apartment and slammed the door shut.
"Leonard?"
"Yes Howard?"
"What just happened?"
"God, I don't know."
Fifteen minutes passed of confused chatter and glaces at the door before Sheldon walked back through it adjusting his shirt.
"Soo Sheldon.."
"Yes Leonard?" For the first time he noticed the room staring at him. "Is something going on I don't know about? Oh are we playing a game?"
"I don't know Sheldon is something going on?"
Uneasier and confused Sheldon had trouble forming a response. "That's why I asked you." He had trouble forming a response, didn't mean he didn't form one.
That seemed like a good time for everyone to go home. They'd get the gossip tomorrow at work anyways.
With all their company gone, Leonard was determined to get to bottom of it once and more all.
He knocked on Sheldon's door and waited for him to open it. A minute and new shirt later access was granted.
"Yes Leonard?"
"Are you or are you not having sex with Penny?"
"Don't be ridiculous, of course I'm having intercourse with Penny."
Leonard thought he was prepared for the yes, he wasn't.
"Leonard? Bazinga. You guys never see my practical jokes coming do you?"
"I'm, I'm just going to go to bed. Night Sheldon."
"It's only eight thirty."
"Good night Sheldon."
