Do you know The Big Bang Theory characters well? Find out with this "who said it?" quiz!

The Big Bang Theory has some of the funniest and most iconic characters on television. The writers did such a great job of giving each of them memorable lines that fit each characters' personality. With 12 seasons under the show's belt, that's a lot of quotes to remember. But if you're the ultimate TBBT fan, I have faith in you. Can you remember all these lines from the comedy series? Put your knowledge to the test with our The Big Bang Theory 'who said it?' quiz!

Alright, how did you do? 15/15 right? The popular sitcom may have started with the main core group of five cast members and characters - Jim Parsons as Sheldon Cooper, Johnny Galecki as Leonard Hofstader, Kaley Cuoco as Penny, Kunal Nayyar as Raj Koothrappali, and Simon Helberg as Howard Wolowitz - but it eventually grew into adding Melissa Rauch as Bernadette Rostenkowski and Mayim Bialik as Amy Farrah Fowler. And it's so great that it did!

The main five were definitely able to hold the show on their own, though Bernadette and Amy were wonderful additions to the cast. And what's great is that each of the characters are different, so it doesn't feel like we ever had two that were the same. Each one brought their own hilarious and unique personality to the table, and it was the talented cast who was really able to bring them to life and give us the comedic gem we have today.

Of course Sheldon has some pretty memorable and funny lines (take this Shelon Cooper quiz to test your knowledge!), it just goes with his peculiar personality. Though the other ensemble cast members also had some great lines, and their delivery was on point! One that always makes me laugh is "You better find my husband's mother, because one way or another we're walking out of this airport with a dead woman." Of course this is Bernadette speaking. It was always funny to see how sweet she is, but she'll turn tough and intimidating when she needs to. And when her voice deepens, you know it's serious.

Another favorite of mine is Penny's Toy Story vows to Leonard at their wedding. It was very Penny like to not be prepared and not have written any vows. But that doesn't mean she doesn't know how or what he loves. And she nailed it. Those were clearly the perfect words based on the waterworks that got going. And really, I shed a few tears as well.

All 12 seasons of The Big Bang Theory are streaming on Max.
