Here is a small side story. Here is what if Leonard scared Penny. Got the idea from my husband watching "Ghost Adventures." I don't own TBBT nor Ghost Adventures.
Popcorn
Penny was home by herself. It was a Saturday evening and she had been working on her new sales pitch since Leonard left at two to fix his laser. Penny had dinner with Amy and Sheldon, but came back early due to she had did not want to be involved the lastest science discussion between those two. Penny noticed it was eight at night and was getting hungry again. So she decided to finish her pitch Sunday and make her favorite snack, popcorn.
Once she threw the bag in the microwave, Penny poured her a glass of wine. She decided to let the bag of popcorn cool down for a minute, Penny went to the bedroom and got her pajamas on.
As she was ready for bed and came back out she decided to watch a movie. So Penny sat on the couch with her snack and her favorite drink. After five minutes she settled for the television show, "Ghost Adventures." Certainly a show Leonard would make fun of her if he caught her watching it, he would tell her ghost were not real. The paranormal was fiction to Leonard just like his comic books were. But tonight Penny was in a mood to be scared. So she turned off her lights and sat in Sheldon's spot with her legs tucked under her while the bowl of popcorn in her lap and the glass of wine on the coffee table.
Leonard was hoping Penny would not be too upset he was just coming home at ten at night. They had plans until Friday afternoon one of his grad students messed up his new laser. So their plans got moved to Sunday.
He slowly opened the door to be quite an noticed all the lights were off but saw the television was still on. As he opened the door more he saw Penny was really into whatever she was watching. So he quietly shut the door and kept watching, Penny's eyes never left the television and kept eating her popcorn. Leonard walked behind her and noticing she was watching one of those reality haunting shows. He just shook his head with an eyeroll that his wife believed this stuff. Then a smug smile spread across his face. He slowly laid his hands on her shoulders and leaned over her ear and whispered into ear as quick, "Hey I'm home."
Next thing Leonard knew was popcorn went flying in the air as did the bowl and Penny flew off the couch with a high pitched scream. The light flipped on, Penny looked pissed with a, "You're an ass!" Then the bowl came down and hit Leonard on top of his head.
Penny burst out laughing as she came to her husband. She made sure he was okay as Leonard rubbed his head. Then they looked around the floor with popcorn spilled all over. "Dammit Leonard, all my popcorn is now wasted."
Leonard pulled his wife into him. "I'm sorry. How about I will buy you a big bucket tommorow when we go see the movie?"
Penny raised an eyebrow with an unamused look on her face as she crossed her arms. "Fine, but as for right now you're going to clean up my popcorn. That way I get to watch the cute tussie of yours, since you decide to scare me."
