I think that the Jersey Shore cast would be hilarious. penny would probably be stoked and all the rest would think they were complete losers!

Chuck would fit right in with the gang!

Walter would probably fit in. The guys could help him with his cow.

I think Lightman would terrify the whole group LOL, and Sheldon will start having those nervous ticks he has when he doesn't get a word in on a conversation hahahaha

I think that Lisa Kudrow should appear as Penny`s mum

@shenelopefan haha, that is actually quite brilliant, I can see them working well together. I would also love to see maybe Stephen Hawking, because Howard mentions him a lot on the show. Maybe even Bill Gates haha imagine him and Sheldon in the same room together...

"Hi I'm Bill Gates"

Sheldon's reply,

"Windows 7 is more user friendly than Windows Vista...I don't like that"

-.- lol

Spencer Reid from Criminal Minds. He's so much like Sheldon. The eidetic memory and the IQ but their attitudes are very different. Sheldon is narcissistic and a dictator while Reid always gets shushed by his team members. haha!

I don't know who she'd play (maybe another attempt at landing Raj a girlfriend after Lucy) but Felicia Day would be totally awesome!
