As Penny walked up the stairs hand-in-hand with Leonard, she felt fulfilled. They had just come back from a double date with Sheldon and Amy Farah Fowler, who had insisted they were just going as friends. She loves "Shamy," as she called them, much to their annoyance. She was glad Howard and Raj had introduced them. She was so deep in thought she didn't notice she was at Leonard and Sheldon's apartment.
When they got to the door Leonard got her attention by asking her where she was staying, code for "Do we need to tell Sheldon to get out his earplugs?" "Does this answer your question?" she said while taking off his tie to hang on the door. He grinned and nodded, and they walked into the apartment blissfully. They had just gotten inside the door and Penny had an idea. "Wanna make out in Sheldon's spo-" she said as she heard the door slam behind her.
"Have you forgotten about my Vulcan hearing? You will not have coitus, or even 'Make out' as you call it, in my spot. I will find out, because the cushion balance fit to shape my buttocks will be off." Leonard and Penny sighed. "I'm assuming I will need to get my ear plugs out, since you have brought Penny here and it appears that you two have planned to engage in coitus." Sheldon then went on to state the roommate agreement about roommates bringing women home.
"We were going to put a tie on the door Sheldon" Leonard informed him as he carried Penny back the hall.
"Goodnight Moon pie!" Penny called to Sheldon as they escaped more of Sheldon going on and on about "Coitus on his spot"
The Next day was a Sunday, and Penny was awakened to hear "But it's oatmeal day!" as she got up, she heard Leonard reply "But Penny wants chocolate chip pancakes!" She walked out to the kitchen to see A plate of chocolate chip pancakes and bacon waiting for her. She walked up and gave Leonard a kiss and noticed Sheldon sulking, eating some of his "High fiber" cereal and watching Dr. Who.
"Ah, Penny," he said, "I see your up. Do you know you have thrown my whole digestive system out of line by expressing to Leonard your desire to eat Chocolate chip filled pancakes on an oatmeal day?" "Ah, Sheldon, do you know no one cares?" " Penny, my digestive system cares." Since she knew there was no point in arguing, she sat down to breakfast. "So Leonard, how is work?" Penny asked uninterestedly. "oh, you know, work." "That's good." Penny got up and said "Well, I'm working a second shift, so ill see you guys later!" "Bye" said both Leonard and Sheldon.
