The Big Bang Theory was extremely popular for many reasons - the pop culture references, the scientific lingo life lessons, and even the hilarious situations the characters often found themselves in. But the biggest selling point had to be the romantic interactions. From Howard and Bernadette to Sheldon and Amy, we just couldn't get enough of all the love.
One couple who became the modern day Ross and Rachel were Leonard and Penny. Their similar will-they-won't-they relationship was often at the centre of most storylines. From the very first episode, to the very final episode, Leonard and Penny were fan-favourites for many. Their love was a definite fairytale. Well, most of the time anyway!
After 279 episodes, Leonard and Penny shared a lot of cute moments, but the question is, just how well do you remember them? Can you remember which episode they shared their first kiss? What about their wedding vows?
Only the most diehard Big Bang Theory fans will have a chance at scoring full marks on this true or false quiz. Are you for the challenge?
