Top 10 Big Bang Theory Episodes

The Top Ten Big Bang Theory Episodes

1 The Staircase Implementation

Young Version of Every Character.

I watch this repeatedly it's so funny - LegoGeek21

The pants alternative should be #1

The upside down flag. Perfect.

2 The Adhesive Duck Deficiency

It was a hard choice between this and the Staircase Implementation but I had to choose this because this one is just funnier. Sheldon and Penny going to the hospital and Leonard Raj and Howard getting high is just classic. I loved every minute. I would write my favourite quote from the episode but there's too many. So I'll go with this one.

"When was your last menstrual period? "
"Next question! "
"I'll just put 'in progress'."

This is my all time favorite! Sheldon getting penny dressed and then when he has to fill out her forms in the hospital! Then they both sing soft kitty at the end as a round! Love it! Love it! I never get tired of this episode!

Funniest episode by far. Maybe the best episode made of any show ever. I can watch this over and over and never get bored.

Funniest episode! Just hilarious. Raj talking with an American accent is priceless. From start to finish I still laugh the whole way through.

3 The Lizard-Spock Expansion

Rock, Paper, Scissors, Lizard, Spock

4 The Lunar Excitation

Zack is funny here :D

5 The Bat Jar Conjecture

This episode is hilarious because the Leslie- Sheldon relationship. 10/10

This episode is just classic. You've gotta love the PMS (Perpetual Motion Squad) and the AA (Army Ants).

Howard ripping off his shirt 😂

It's on bitch!

6 The Cooper-Nowitzki Theorem

Love this episode. Best quote is when Romana drives Sheldo crazy for too long and this is the quote
“Dr. Cooper has just had a breakthrough! ”
“Oh I couldn’t have done this without you.”
“Oh please.”
“Seriously you helped me work out the math and the neutrinos. How can I repay you”
“Would you consider naming this The Cooper-Nowitzki Theorom? ”
“Who’s Nowitzki? ”
“I’m Nowitzki.”
“Oh you want me to share credit? ”
“GET OUT! ” - steelers1979

7 The Barbarian Sublimation

This episode is great because it is the one time that Penny understands how much the guys like their games and, in a way, becomes one of them.

8 The Justice League Recombination

As a geek, I loved this episode.

9 The Closet Reconfiguration

" sheldon, that's the plot from the goonies " laugh out loud

10 The Precious Fragement

This one is great

The Contenders

11 The Euclid Alternative

Sheldon on the back of Howard's scooter is the best Sheldon Cooper moment!

This is also one of my favorites! Hahaah

12 The Spaghetti Catalyst
13 The Tangerine Factor

I could not get myself together after Sheldon's encounter with the man at the Chinese food place by far the best episode, plus this is when Leonard asks penny out for the first time.

14 The Pancake Batter Analomy
15 The Countdown Reflection
16 The Zarnecki Incursion
17 The Scavenger Vortex
18 The Robotic Manipulation

I can't believe that wasnt on the list.


19 The Bath Item Gift Hypothesis

Before this episode Sheldon and Penny were just polar opposites, they could barely communicate or even stand each other, plus they had a huge fight only 4 episodes before this one, so the fact that Penny gave him such a meaningful gift and moreover Sheldon's definitely unexpected reaction put their relationship in a whole new light. Throughout the years they became the best friends ever, helping and sustaining each other in times of need (from the episodes where Sheldon lent her some money to pay her rent or where he helped her with the Penny Blossom business, both shortly after this one, to the very end when she made him reflect about the inevitability of change, including many others in between) and understanding each other way more than anyone else, but without stopping arguing and mocking each other continuously, exactly as if they were brother and sister. This episode was amazing both in itself and for what it started: the most unpredictable yet arguably best friendship in the ...more

Adorable. The revelation of what Penny's gift really was, Sheldon's overwhelming realization that she truly knew him and what he valued, his gratitude and generous all-in response -and the hug. Priceless.

Why isn't this number 1? It's got so many funny lines, and Sheldon hugging Penny. There are other good ones, like the guys getting stoned, etc, but this is number 1

This has Sheldon hugging Penny in a weird way this episode is so funny

20 The Parking Spot Escalation

I like this one some stuff that happen in this episode is something you don't see often in this show the characters outside for once Howard naked on Sheldon couch Sheldon naked in Howard car Amy breaking Penny nose I was a little surprise when that happen it was really funny and one of the best episodes of the show

How is this not number 1? I've watched many, many episodes, and this one makes me howl every time. I love the whole scene where Sheldon is "using" his space the most, but the rest of the episode is great, too, right down to the Bernadette-Amy quips.

This is the only episode I've seen penny get hurt and it so funny and my favourite episode

It's the girls that have all the best lines

21 The Toast Derivation
22 The Focus Attenuation
23 The Zazzy Substitution

The look on Sheldon's face as he says 'but he's just so...Zazzy' never fails to crack me up. My absolute favourite episode. - truckturner

"but he's just so... Zazzy." - keycha1n

24 The Cooper-Hofstadter Polarization
25 The Einstein Approximation

Sheldon in the ball pit one of the best bazingas ever

26 The Luminous Fish Effect
27 Pilot

"Our babies will be smart and beautiful"... I find very moving that it happened exactly in the series finale, and it's even more moving that Sheldon reminded Leonard's quote in his Nobel Prize speech. I've rarely seen something coming full circle so perfectly.

I respect it for setting up a good series and having some great jokes, but to be honest the writing and characterization aren't that great.

Really good intro to the world of TBBT! Great writers. It felt like the charachters were real people who we knew our whole lives! :-)

28 The Big Bran Hypothesis

A great early episode. Far better than the pilot.

29 The Vengeance Formulation
30 The Creepy Candy Coating Corollary
31 The Egg Salad Equivalency

This is my new favourite episode. It was my new favourite when I first saw it; before that, I never thought they'd be funnier than season 4. It's normally hard to speak for an entire season by comparison with one episode, but this episode beat it! Excellent! - PositronWildhawk

This episode is the first properly funny and properly awkward episode since "The Robotic Manipulation" had me choking with laughter. This one was the absolute best; no question at all.

32 The Bad Fish Paradigm
33 The Infestation Hypothesis
34 The 21 Second Excitation

The the the the the the the... enough said

35 The Ornithophobia Diffusion

A blue jay sits on there window sill (sheldon is afraid of birds), but eventually he gets over it. The part where the bird sits in Sheldon's spot is hilarious.

36 The Thanksgiving Decoupling
37 The Pants Alternative

How is this not #1, I roll around the floor laughing when I watch this episode.

38 The Gorilla Experiment

I'm surprised no one has mentioned this episode. This was hilarious. Sheldon teaching Penny physics is definitely one of the best scenes in the series - lucyb247

39 The Romance Resonance
40 The Plimpton Stimulation
41 The Killer Robot Instability
42 The Classified Materials Turbulence
43 The Love Car Displacement
44 The Stag Convergence
45 The Cruciferous Vegetable Amplification


46 The Indecision Amalgamation

I love the ending

Hilarious plot
Laughter all through!

47 The Hawking Excitation

I love, love, LOVE this episode! This, The Weekend Vortex, The Good Guy Fluctuation, and The Engagement Reaction are among my favorite episodes of the show!

I just love sheldon taking Mr. Holowitz clothes shopping and pee pee proofing Howard's belt buckles.

48 The Shiny Trinket Maneuver

Everybody gets cake! - Howard
Not him! -Bernadette

49 The Friendship Algorithm
50 The Higgs Boson Observation

Howard starts cracking up in space. Sheldon hires an assistant.
