Top 10 Big Bang Theory Episodes


The Top Ten

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

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

Amazing. The brother-sister relationship between Sheldon and Penny starts here, that Soft Kitty scene is fantastic.

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!

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 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.

13 The Pancake Batter Analomy
14 The Spaghetti Catalyst
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 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

20 The Toast Derivation
21 The Bath Item Gift Hypothesis

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


22 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

23 The Focus Attenuation
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 The Big Bran Hypothesis

A great early episode. Far better than the pilot.

28 The Vengeance Formulation
29 The Creepy Candy Coating Corollary
30 The Bad Fish Paradigm
31 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.

32 The Thanksgiving Decoupling
33 The Pants Alternative

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

34 The Romance Resonance
35 The Plimpton Stimulation
36 The Killer Robot Instability
37 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.

38 The Classified Materials Turbulence
39 The Love Car Displacement
40 The Stag Convergence
41 The Cruciferous Vegetable Amplification


42 The Infestation Hypothesis
43 The Indecision Amalgamation

I love the ending

Hilarious plot
Laughter all through!

44 The 21 Second Excitation

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

45 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.

46 The Shiny Trinket Maneuver

Everybody gets cake! - Howard
Not him! -Bernadette

47 The Friendship Algorithm
48 The Higgs Boson Observation

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

49 The Hot Troll Deviation
50 Pilot

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! :-)
