I think the coolest cameos was when Sheldon was listening to the Nobel prize on the radio. The gang as kids were either sleeping and or up doing what kids do. I so wanted them to somehow talk to each other. It was a bitter sweet ending to the episode. I guess the cameo of the characters. Ray liotta was dope.

I was surprised to see Steve Burns from Blue's Clues on here!

[@KingdomofEvania100]

He does the show theme song

[@amymartin9424]

I was surprised to see Steve Burns here too! He's my all time favorite actor! I loved Blue's Clues so much and I still do! It always helps cheer me up no matter what! I had and still have a huge crush on him. 😊

[@XJIcequeen]

Steve Burns is a saint

[@JYang0602]

Okay I knew the character he played that the actor looked familiar as hell but realizing it’s MF Steve from Blue’s Clues AND that he is the Theme Song writer/singer is just so crazy man

[@trinaq]

I love that McKenna Grace has been receiving more work, especially as the younger versions of main characters. She looks uncannily like Kiernan Shipka, and I wouldn't be surprised if she eventually gets her own younger version.

[@the_glitter_is]

She's a phenomenal actor

[@trinaq]

I love Melanie Lynskey, her American accent is very convincing, that I was surprised to hear her natural New Zealand accent in an interview. It's great to see her in another Chuck Lorre show.

[@leonardoolivares924]

Mary: What’s your name? Dusty: Dusty! Mary: That’s not a name, that’s a poorly kept house… This will NEVER not be funny lolololol

[@NickCC23]

[@orbitaldragon]

Wow.. I had no idea that was Steve Burns from Blues Clues.

[@pariston1284]

Isnt it Professor Proton? Why did they call him Captain Proton at the 12min mark?

[@Ooobydoobydoo]

While not a huge fan of Elon Musk, but I loved his cameo on the show. I found it funny how he portrayed himself as getting his ideas from a 10-year-old’s work.

[@carmenarenas7691]

Ray Liotta and Elon Musk were the best cameos for me.

[@GamerFunOriginallyAarush]

That’s what is up!

[@jakelauto6304]

You know, that’s the first time you mentioned Bubble Guppies in one of your videos (the part of this video when you talk about Wendie Malick).

[@TOP5InstantRegret]

Your video is a captivating journey through time, seamlessly blending the timeless charm of 1960s Hollywood with the inspiring life stories of these cast members in their contemporary roles. *DO YOU AGREE WITH ME*

[@Emmaleegossardgossard-ig6xl]
