When Penny met Leonard for the first time, she wasn't instantly attracted to him. She thought of him as her neighbour/friend, someone who would sign for parcels and invite her over for a takeout now and again. Leonard however was the complete opposite. He had a massive crush on Penny and would make sure his friends knew all about it.
Over time, Penny began to realise how Leonard felt and the more these two spent time together, the closer they became. It wasn't always a smooth ride however, the two often arguing over sometimes the smallest of things. However, they managed to stand the test of time and become one of the most beloved couples in television history.
Their story might not be as well known as Ross and Rachels, however TBBT fans would argue that they were definitely the better couple.
Do you know Leonard and Penny better than they even know themselves? After 12 seasons and 279 episodes, there was a lot to learn about these two. Just how closely were you paying attention?
