Friday at 6:55, Penny knocked on the guy's door. Her attention was on a bandage she was affixing to her wrist, so she didn't notice Sheldon's reaction when he opened the door.

He took in the brown leather boots that rode over skin tight jeans dispassionately. It was the shirt that caught his attention. It was the same green as her eyes and read "Higgs Boson Gives Me A Hadron". It was low cut and tight, revealing her figure nicely.

Sheldon swallowed the lump in his throat and blinked several times.

"Hello, Penny. You are right on time." He frowned when he noticed the bandage. "Have you hurt yourself?"

Penny shrugged. "Got burned by a stage prop. Tesla coil shorted out. It's nothing major." Sheldon took her elbow and lead her to the couch. Leonard and Howard were sitting on chairs and Raj was at the end of the couch nearest the door. Penny sat down in the middle and Sheldon peeled the bandage away from her skin. He walked toward the kitchen and took the first aid kit from the cabinet. The guys were watching with stunned expressions as he sat down on the table in front of Penny and began spreading an aloe based burn cream on the 2 inch blister. Then he carefully wrapped it in gauze.

"An adhesive bandage is not optimal for a burn. It will seal in moisture from the blister and take longer to heal, not to mention the increased likelihood of infection. Gauze will keep the area clean while allowing it to breath." He cleaned up the mess and took the kit back into the kitchen.

"Thanks Sheldon," Penny said as she flexed her wrist to make sure it was comfortable.

"Umm, so a Tesla coil?" Leonard questioned. "You said it's a stage prop?"

Penny nodded as Sheldon sat down and began handing out the meals. "Yep. A one night production of Young Frankenstein at the Pasadena City College. The drama club is doing a month long classic movie monsters tribute in two months for Octoberfest. Rocky Horror Picture Show, Dracula's Castle, Wolfman, and so on. I think we'll also be using it for Plan 9 From Outer Space, but I'm hoping to find a smaller one for that. The one we have is 4 foot tall and more likely to burst into flames than a whore in church."

Howard choked on his General Tso's Chicken and Leonard had to swat him on the back a few times. Penny blushed. "Sorry. Working with college students always brings out the foul mouth in me. Students don't pay any attention to you unless you can out drink them or out cuss them. And it was too early in the day for rum."

Penny turned to Raj. "So, what do you do sweetie? I don't think we've ever really talked before."

Raj squeaked and looked at the floor. "You'll have to forgive him, Penny," Sheldon said with a sigh. "Raj has selective mute-ism. He is incapable of talking to available women."

"But don't worry," Howard said with a leer. "You can have all the conversation you want from me. Actually you can have all you want of anything from me." He wagged his eyebrows at her suggestively.

"How about quiet, then," she teased.

"Sugar, I'm sorry to disappoint, but I'm never quiet. Especially in bed. Would you like to see?"

Sheldon and Leonard both glared at Howard who was unabashedly ogling Penny.

"Well," she said with a smile, "that's a …..kind offer. But I'm more of a clits, not dicks kinda gal."

Everyone looked at Penny in confusion. "You mean you're…" Leonard let the sentence trail off, not sure he could ask. Definitely sure he wouldn't like the answer.

Penny nodded. "Yep. Gay as a rainbow colored fishnet shirt." Penny continued to eat, ignoring the stares and open mouths around her. None of the guys spoke for several moments.

"I am an astrophysicist," Raj blurted out suddenly. He looked as surprised as the other guys did.

Penny frowned a bit. "What does an astrophysicist do?" Raj smiled at her, happy he could converse. He proceeded to explain his job as they ate.

Sheldon glanced at Penny several times. He had never really known any lesbians before. He had nothing against homosexuality per se, but he was startled to find he felt a bit of disappointment that Penny was one. The meal passed quickly and the guys began playing Dragon Warrior 3 for the Nintendo system. Throughout the game, the guys asked Penny about the plays she worked on and she asked them what they all did. She even played a level, and did fairly well.

At 9pm sharp a knock on the door made Sheldon pause the game. Penny stood up quickly and smiled warmly as she headed for the door. She opened it and they heard murmuring. After a second or two, Penny pulled a brunette into the room. She wasn't exactly what any of them had expected from a friend of Penny's. She wore a long tan skirt and a brown sweater over a crisp white button up shirt. Her hair was long and hung down her back, and she wore glasses. However there was no mistaking the pleasure in Penny's face as she looked at her friend.

"Everyone, this is Amy Farrah Fowler. Amy, meet Sheldon Cooper, Leonard Hofstadter, Howard Wolowitz and Rajesh Koothrappali." Penny had slipped an arm around Amy's waist and Amy had moved in close to Penny, practically fusing their bodies together. Amy nodded to each one and then smiled up at Penny.

"Are you ready?" Amy asked in a calm quiet voice. Penny nodded and then gathered her dinner container to throw it away.

Sheldon stood and walked forward. "It is a please to meet you, Amy. Have you and Penny known each other long?"

Amy shook her head. "Only 11 weeks. A mutual friend set us up in a blind date. We immediately hit it off, though."

Penny came back over and placed her hand in Amy's. "Thanks for having me over, guys. I had fun. See you around soon." The women headed for the door, but Sheldon stopped them again.

"Penny would you and Amy like to join us for dinner on Sunday? We will be having pizza and watching the movie The Avengers," he asked pleasantly. "We would be happy to include the two of you."

Penny looked at Amy who seemed to consider it and the nodded. Penny grinned widely and turned back to Sheldon. "Thanks sweetie, we'd love to. What time?"

"We will eat at 6," he said calmly. "Have a good evening ladies. We will see you Sunday." Penny and Amy nodded and then left.

"I was really hoping she was lying about the gay thing," Howard said sadly.

Raj shook his head. "Nope. I could talk to her. She's definitely gay."

"Great." Leonard lamented. "I finally meet the perfect woman, and she's just as interested in women as I am."

Sheldon remained quiet. He wondered what kind of person Amy Farrah Fowler was to have attracted Penny's attention. He didn't look too carefully into why he wanted to know. That way lead in an uncomfortable direction.
