My favorite YS episode is the Nobel Prize Party nobody came to the ending where you see his future friends as children themselves makes me smile especially Howard's mom yelling at him may she rest in peace

This young Sheldon kid is amazing. He could mimicking all Sheldon's mannerisms by mid season 1. I really enjoyed this series

The first meeting of Professor Proton and Penny was one of the best scenes of either show. When he says to Leonard
'' she's your girlfriend?"
.." then YOURE the genius."

I feel like there was a time Missy was watching “Blossom.” Sheldon said he didn’t know who that was, Missy, replied, “Someday you will.”
Does anyone else remember this because I thought it was a great tie-in to Amy Farrah Fowler on TBBT.

I never would've expected to see Steve AND Arwin in the same scene on that bus! It was awesome!

I always enjoy Mckenna Grace as Paige, Taylor Spreitler as Sam, Brian Stepanek as Mr. Givens and Isabel May as Veronica.

Holy heck I didn't realize that that was Steve from blue's clues

Unpopular Opinion: I actually like the prequel more than "Big Bang Theory." Maybe it's because of the lack of laugh track, the charming performances of the ensemble cast, getting to see Sheldon as a precocious child or the nostalgic setting. And now it's getting renewed for at least three more seasons.

The irony of the 2 shows is that Young Sheldon is about a child who acts like an adult and TBBT is about an adult who acts like a child. 2 shows about the same character.

I feel like we should note that Sheldon’s dad played Leonard’s childhood bully in big bang theory

[abigailaceves]

The quest appearances of Kaley Chico, Mayim Bialik & Simon Helberg certainly did surprised me.😊
Thank you, MsMojo, for this list.

It's always fun to see Jason Alexander pop up as a drama teacher, considering his impressive theatre background. And Reba must have had fun pretending to sing badly!

[tbecker]

Teller was *also in The Big Bang Theory* as Amy's father. Kathy Bates played Amy's mother.

RIP Lance Reddick. You were a great commander of us Guardians. We shall continue to fight on in your memory and honor.

As a fan of Big Bang, I struggled a bit with Young Sheldon at first. But now I'm really into it and I like the series very much.

Ray Liotta trying to collect a debt from Me Ma is priceless. Love em' all but that one had me!

[bamabarrelracer]

Puss later becoming Sheldon's Father-in-Law❤😂❤

[sydneyscout]

Having Steve was brilliant! Especially with the theme song being performed by his band. My 4 year old self died seeing him ❤

[petejones]

Elon Musk was in an episode where he was in a kitchen washing dishes in Tbbt... And Teller played Amy's father again in Tbbt

[coffeeperson]

Steve Burns is amazing. Playing both kids show guy and creepy guy you don't want near your kids. It's hard to even tell it's the same guy
