Big Bang Theory: The Best Part Of Leonard And Penny's Relationship

Throughout the 12 seasons of "The Big Bang Theory," audiences witness several relationships develop, including Sheldon Cooper (Jim Parsons) and Amy Farrah Fowler (Mayim Bialik), and Howard Wolowitz (Simon Helberg) and Bernadette Rostenkowski (Melissa Rauch). However, arguably no pairing was more unexpected than that of Leonard Hofstadter (Johnny Galecki) and Penny (Kaley Cuoco).

From the pilot episode in 2007, which sees aspiring actor and Cheesecake Factory server Penny move in across the hall from Leonard and Sheldon, the experimental physicist is attracted to her. Though Penny initially only sees a platonic friend in Leonard, she soon realizes that he's a good guy and exactly what she needs in her life. 

Over the course of the series, the two experience their share of struggles, from their brief separation to Penny's hesitance to have a baby, something Leonard always dreamed of. Despite their rocky road to love, they enjoy a happily ever after. Let's take a look at the best part of Leonard and Penny's relationship.

Leonard and Penny are a perfect example of how opposites attract

It's no secret that Leonard and Penny are polar opposites. While Leonard is a smart, nerdy physicist with a passion for "Star Trek," Comic-Con, and playing Mystic Warlords of Ka'a with his friends, Penny is a bit more focused on superficial pastimes (at least when we first meet her) and didn't attend college in an effort to pursue an acting career.

At first, neither feels like they're good enough for the other. Leonard frets over not being Penny's typical "bad boy" type and Penny convinces herself that he'd prefer someone more intelligent. However, their differences allow them to learn from one another and keep things interesting. This is the beauty of their relationship, which shows that opposites do attract, unlike Sheldon and Amy, who oftentimes have issues because they're so similar.

On Reddit, u/Elcapitan2020 said, "He's helped her become more worldly, sophisticated and mature, she's helped him grow in confidence...that's what a couple should be." Meanwhile, u/8Frenfry_w_ketsup added, "They compliment each other. Yin yang. No couple is perfect, ever. I wouldn't want to marry myself. Once dated someone just as analytical as me. What a drag." And for u/monkeychango81, the beauty of the relationship lies in how "they were so 'incompatible' but they ended together and loving each other."
