I dont believe Mayim Bialik can ever get enough credit for what she brought to the show. She brought so many different levels of character that there is something for everyone, not to mention she is super funny. Love her in this role.

The "B*tch coin" blooper made me laugh way more than it should have lol

[lauraodenwaldt]

Johnny Galecki’s reaction to Kunal’s slip up for Bitcoin was priceless!

I watch this show at least 2 hours before I go to sleep. I don't know how many times I've watched it from start to finish, but this has become a big part of my life and I love every episode. 🥰

When Kunal and Simon sang at the comic book store, I laughed at the outtakes because Kaley couldn’t hold it. Can’t blame her though. But the spanking scene is the icing on the cake. Jim is so cute when he breaks into laughter.

Jim Parsons trying to get through "Rock, paper, scissors, lizard, Spock" was a favorite

[ashleymclaughlin]

My favorite is when Sheldon asks Penny about friends with benefits. And she tells him that her and Leonard are just benefits.😂

[soloflight]

Oh, what therapy this show is. I have such great love for this cast and was heartbroken when it ended. ❤

[easye]

I don't know how Jim Parsons could keep a straight face while spanking Mayim! Hilarious. 🤣😂

[Nitroxme]

The Vicks rub cracked me up. I fell off the couch laughing!

[NeddyMontz]

19:24 Sheldon spanking Amy 🤣🤣🤣🤣🤣🤣 I couldn't keep a straight face while watching the blooper. 19:59 cracks me up every time

[lpayjohn]

One of my favorites is when Penny gets the chair from the curb and Sheldon tries to get her to throw it out and he knocks on her door and she puts the cushion in his face and he runs away screaming

[precious_muse]

One of my favorites wasn’t on the list. Sheldon says something outlandish, and Penny is scripted to say, “Are you high?” Then Leonard says something, but Johnny flubbed his line, so Kaley looks at him and says, “Are YOU high?” Then later she flubs her own line, and Johnny just points at her and says, “High!”

[adamjones-ps]

"Then maybe you should spank me harder" was the funniest line in the entire show. I laughed so hard at her delivery I was in tears. Such a great show. They were smart to go out on top.

Never again we experience another sitcom like this!❤❤❤

[AprilScott-kefn]

I was so impressed how Jim could remember all his lines.

[Gfriend_Buddy]

The spanking blooper should won an award... 😁

[nicolepowell]

Number 5 all the time. Amy sick was amazing and so hilarious to watch

[eduardomenna]

8:37-9:28 👏 The audience is like "what?" and Galecki is like when you hear something wrong, freezes in place and slowly turns your head back

[kiara_reddy]

Love this, but you left out the classic ‘Rock, paper, scissors, lizard, Spock’ blooper 😂
