Another aspect could be Penny's family. Fanfiction could explore what happens when Penny's family from Nebraska visits and how the guys interact with them. Maybe there are some comical situations where Penny's parents misunderstand the guys' scientific work, and Penny has to mediate. These stories can be really interesting and family - friendly.
Penny's decision to go back to school was also a significant moment. It showed her determination to better herself and grow as a person. Her struggles and successes in her academic journey were quite inspiring and added a new dimension to her character that had nothing to do with sexual content.
There could be a fanfiction where Penny's pregnancy makes Leonard super nervous. He starts freaking out about being a dad and all the responsibilities. Meanwhile, the rest of the gang tries to support them in their own clumsy ways. It's interesting to see how the characters' relationships develop during this big life change.
A theme that is often explored is Penny's role in the group dynamic. In some fanfictions, she becomes the mediator when the guys have arguments about scientific theories or comic - book universes. This shows her importance in the group and how she helps keep the peace, without any sexual elements involved.
Some Penny x OC fanfiction focuses on the OC being a musician. Penny, with her love for music and performing arts, is drawn to the OC. They could start collaborating on a musical project together. Maybe the OC writes a song for Penny to perform, and through this process, they develop a deep connection. It's a fresh take on Penny's character and adds a new dimension to the Big Bang Theory universe.
Another story could be Penny's efforts to bond with Bernadette and Amy. They had some great adventures together, like going shopping or having girls' nights out. These stories focus on female friendship and the dynamics within the group, which are quite engaging and fun to follow.
One appropriate topic could be their adventures in scientific experiments together. For example, they could be collaborating on a project where Penny's practical skills and Sheldon's theoretical knowledge combine in a comical yet productive way.
There are many relationship - based stories in 'Big Bang Theory'. For example, the on - again - off - again relationship between Leonard and Penny. Their relationship had its ups and downs, from their first meeting, Penny being the beautiful neighbor that Leonard was smitten with, to their various breakups and reconciliations. Another interesting relationship is that of Sheldon and Amy. Their relationship evolved slowly, starting from a very unusual beginning where Sheldon was quite resistant to the idea of a romantic relationship. But over time, they grew closer and had many sweet and funny moments together.
As far as I can remember, there is no such Penny wedgie incident in The Big Bang Theory. The series was filled with different kinds of comical situations. For example, there were Sheldon's idiosyncrasies, Howard's attempts to pick up women, and Raj's selective mutism. But a wedgie incident for Penny just doesn't seem to be part of the storylines.
There are numerous funny moments. One is when Sheldon tries to teach Penny about physics concepts in his own unique, overly - complicated way. His facial expressions and the way he gets frustrated when Penny doesn't understand are hilarious. Another is when Howard wears his astronaut suit in inappropriate situations, like when he goes to a regular party. It looks so out of place and makes everyone around him react in a really funny way.
The scientific adventures of the characters are also a big part of it. Their work at the university, their research projects, and their attempts to make scientific breakthroughs. Like when they collaborate on a project about string theory or try to solve some complex physics problems together.
