My Top 20 Episodes of The Big Bang Theory

It's safe to say that I'm a huge fan of The Big Bang Theory. I was introduced to the show by friends and we binge-watched the first four seasons in a couple of days. This was in 2011. I followed and adored the series for eight years. My bedroom was covered in posters of Sheldon and the gang. I had the calendars, t-shirts, notebooks, basically every and any bit of merchandise I could get my hands on. I even had a keyring on my house keys that showed the instructions to 'Rock, Paper, Scissors, Lizard, Spock'. I've spent hours upon hours watching and re-watching every episode - so much so that I'm able to quote some of them off by heart. It was and still is my absolute favourite series that I've watched.

So I feel like the perfect candidate to share my top 20 episodes throughout its glorious 12 seasons. If you haven't seen the show before - something I very much doubt - you can watch TBBT on Netflix in the UK and there's no better time like the present to do a good bit of binge-watching! It was a very hard task, with the show boasting 279 episodes, but I managed to whittle it down after some editing and reshuffling. My only bias is that my favourite characters are Sheldon, Amy and Penny so most of the episodes feature iconic moments of these three.

Let's get started!

Pilot (Season 1, Episode 1)

What better way to start than with the original episode that got everything started? Like any true pilot, the camera quality gives it an old-school feel and the laugh track makes it a little bit awkward. Nonetheless, we are introduced to super nerds Sheldon and Leonard in a fantastic fashion and get to see the beginning of Penny and Leonard's fabled relationship. If you are lucky, you might be able to find the unaired pilot online which features a different cast to the one we know and love. The pilot is completely iconic and an integral part of watching TBBT.

The Middle-Earth Paradigm (Season 1, Episode 6)

This early classic shows the boys testing their social skills when Penny invites them to a Halloween party. Fun fact - this is where I learned about The Doppler Effect, which became very useful looking like a right know-it-all in GCSE physics, thanks to Sheldon's perfect costume choice. It's also the first page of Penny and Leonard's love story when the pair share a short kiss.

The Barbarian Sublimation (Season 2, Episode 3)

When Penny reaches a low-point and feels like she is failing at everything in life, Sheldon tries to comfort her by introducing her to Age of Conan, an online role-playing game. In this episode, Penny becomes one of the guys, and really embraces her inner nerd. It only takes her a short time though to realise she's taken it a step too far and the episode closes with Penny throwing her laptop away in disgust.

The Bath Item Gift Hypothesis (Season 2, Episode 11)

In the show's first Christmas episode, Sheldon struggles with the concept of gift-giving. He's not a huge fan of the winter holiday so finding the perfect present for Penny becomes a struggle, especially when she gives him a gift that blows all others straight out of the water. I'll let the clip speak for itself.

The Adhesive Duck Deficiency (Season 3, Episode 8)

This is, without a doubt, my all-time favourite episode of The Big Bang Theory. Leonard, Howard and Raj get high after eating a bag of cookies whilst camping in the desert. In the secondary narrative, Sheldon takes Penny to the hospital after she dislocates her shoulder in the shower. Filled with plenty of funny moments, this ranks highly as one of the best episodes in TBBT's 12-season history

The Thespian Catalyst (Season 4, Episode 14)

In this episode, Sheldon explores what it feels like to live in Penny's shoes and asks her for acting lessons. This is another memorable moment in their friendship, a bonding moment of sorts for the pair. Meanwhile, Raj keeps having romantic dream sequences involving Bernadette, one of which is a Bollywood-style musical number. It's just as strange as it seems but the song is surprisingly catchy!

The Shiny Trinket Maneuver (Season 5, Episode 12)

Amy and Sheldon's relationship is unlike any other, and they face their first problem when Sheldon is not impressed by Amy's latest scientific accomplishment - something which she is very proud of. With Penny's help, Sheldon tries to gain Amy's affection back. Of course, the only solution is to gift her with a tiara and Amy's reaction is hilariously perfect.

The Werewolf Transformation (Season 5, Episode 18)

Sheldon can't seem to cope when he finds out that his barber has passed away, turning his routine world into chaos. He believes that the best way forward is to live like a hippie to match is shaggy, overgrown hairstyle. Part of this new lifestyle includes playing the bongos, much to the dismay of Leonard and Penny.

The Re-Entry Minimization (Season 6, Episode 4)

Game Night is a classic piece of TBBT history, and what better way to go back to tradition than with a battle between the sexes? From Pictionary to wrestling, Sheldon, Leonard, Penny and Amy find their competitive streaks to prove who is the stronger gender. Side note: I really want a copy of 'Physics Fiesta' to play with my friends.

The Fish Guts Displacement (Season 6, Episode 10)

Even though the episode title focuses on the storyline between Howard and his father-in-law, the best part of it is the scenes between Sheldon and Amy. When Amy gets sick, Sheldon becomes the perfect boyfriend and takes care of her. Amy enjoys it so much that she pretends to be ill for much longer than she should be. Sheldon soon finds out and thinks the best punishment is to spank Amy for her misbehaviour. That's right, spank her.

The Scavenger Vortex (Season 7, Episode 3)

This episode explores the relationship dynamics between the gang when Raj organises an epic scavenger hunt. Sheldon and Penny work surprisingly well together, Leonard and Bernadette face a few problems when Bernadette's competitive side comes out, and Howard and Amy become the best of pals when they bond over their love for Neil Diamond. This another one of TBBT's greatest.

The Locomotive Manipulation (Season 7, Episode 15)

In one of many Valentine's Day chapters, the gang each have their own plans for the February holiday. The most important though is Sheldon and Amy's. Amy plans a romantic weekend for the two of them on board a vintage train but she feels neglected when Sheldon starts to ignore her. The pair experience their first moment of real romance and I would be lying if I said I didn't squeal with joy when I watched it happen.

The Prom Equivalency (Season 8, Episode 8)

I'm not even sorry for choosing another iconic moment in Shamy's relationship because they truly are the best couple on the show. When the girls organise a re-enactment of their high school prom, Sheldon gets anxious to participate in all the normal romantic traditions of the night. Amy makes sure to console him and the pair share their first "I love you". I'm not crying, you're crying!

The Colonization Application (Season 8, Episode 17)

Sheldon and Amy's relationship is once again tested when Amy finds out that Sheldon has applied for a one-way colonisation trip to Mars without her. We all love a bit of angst between your favourite fictional couple and this episode makes sure to have your heart on a rollercoaster if you're a Shamy fan.

The Earworm Reverberation (Season 9, Episode 10)

During Shamy's break-up phase, Sheldon is driven crazy by a familiar tune that he can't figure out. Meanwhile, Amy is continuing to date Dave (guest star Stephen Merchant) who is possibly Dr Cooper's biggest fan. Sheldon discovers the song he has been humming and realises that it's about Amy - the dryer sheets of his heart. Shamy are finally reunited after ten episodes apart THANK GOODNESS!

The Opening Night Excitation (Season 9, Episode 11)

It's Amy's birthday and Sheldon is faced with one of the biggest decisions of his life: go to the premiere of the new Star Wars movie or spend a romantic night with Amy. With the help of Professor Proton as his Jedi Master guide, Sheldon decides that he will consummate his relationship with Amy. This is another one of Big Bang's best and includes some great moments of juxtaposition.

The Brain Bowl Incubation (Season 10, Episode 8)

After a successful gene experiment, Sheldon thinks it would be a great idea for him and Amy to have a baby. She disagrees so Sheldon tries his best to seduce her. If you'd asked me if we'd ever see Sheldon perform the Flamenco, I would have laughed at you but the writers struck gold in this episode.

The Birthday Synchronicity (Season 10, Episode 11)

This episode celebrates two birthdays: Amy's and Howard & Bernadette's baby. Sheldon and Amy keep hitting obstacles trying to have Amy's birthday sex when Bernadette goes into labour. The toing and froing in this episode is hysterical but Amy finally receives her birthday present after a trip to the Wizarding World of Harry Potter - the typical, strange Shamy way.

The Bow Tie Asymmetry (Season 11, Episode 24)

It only took them eight seasons but Sheldon and Amy FINALLY get married! Things go awry when the couple's family arrive but Shamy just don't seem to care. In classic Big Bang Theory fashion, there is plenty of drama and the pair tie the knot at the end of the episode. It also stars Mark Hamill who acts as the officiator of the wedding, the perfect way to finally add Hamill to the list of iconic guest stars.

The Stockholm Syndrome (Season 12, Episode 24)

279 episodes later, The Big Bang Theory reaches its final episode. In my opinion, it's a brilliant way to close the show and includes just the right amount of humour and heart. Each character finds some aspect of closure and the final scene will have you wiping a tear from your eye. No matter how long you followed the show, whether from the beginning in 2007 or binge-watching the series in the last month, it's hard to say goodbye to such an iconic cast of characters. Spoiler Alert for the clip below but it's just too good to not feature.
