I'm gonna go ahead and say it... I don't know how this series will play out for three more seasons. I don't feel like the situations the characters come into are as "everyman" as Friends or Seinfeld, but there's no big gimmick to be revealed like on How I Met Your Mother, either. The close dynamic of Frasier and Happy Days isn't there, and it's not "workplace" enough to work like Cheers or M*A*S*H. But, Two and a Half Men manages to keep finding things to write about, so I suppose there's still humor to be found. One thing is for sure, though... they better find a way to write-in a multiple-part episode with the guys ACTUALLY AT COMIC-CON!
The Big Bang Theory "The Status Quo Combustion" (S07E24): Leonard and Penny share their proposal news with their friends, then their parents, but Leonard's mother already knew, courtesy of Sheldon. [ugh.] Leonard talks to Sheldon about not living together anymore, so he rants to Amy, who suggests that they live together. [basing the wedding on Penny's brother's schedule, it will be 12-18 months from now... good to know.]
Sheldon finds out that he can't change his field of study at the University, as he was hired to do String Theory. He appeals to the faculty senate, but things just start turning sour in every area of his life... and after the comic book store burns down, he heads to the train station, with the intent to ride the rails. [seriously?]
Howard's mom has gone through multiple nurses, and when Penny can't handle the job (at carte blanche), Howard and Bernadette worry that they may end up stuck caring for her... until they realize that Stuart is happy to be Debbie's caretaker, and they take to each other well. [did we previously know Howard's mom's name?]
In other news, Raj has sex with Emily.
