The Top Ten
1 The Staircase Implementation

Great it finally reveals one of the longest mysteries of the sitcom. Why is the elavator broken? Answer watch the episode to find out

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!

3 The Lizard-Spock Expansion
4 The Lunar Excitation
5 The Bat Jar Conjecture

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

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

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? "

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
9 The Closet Reconfiguration
10 The Precious Fragement
The Contenders
11 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.

12 The Pancake Batter Analomy
13 The Spaghetti Catalyst
14 The Countdown Reflection
15 The Scavenger Vortex
16 The Euclid Alternative

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

17 The Robotic Manipulation
18 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 show.

19 The Parking Spot Escalation

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.

It's so great! Sheldon's actually naked in the car!

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

20 The Toast Derivation
21 The Zarnecki Incursion
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.

24 The Cooper-Hofstadter Polarization
25 The Einstein Approximation
