Who stands between Sheldon and his perfect wedding venue?
For Sheldon, its the unlikelihood of having his wedding ceremony on Mars.
Luckily, Amy has a brilliant idea and suggests she and Sheldon marry at The Athenaeum at Caltech.

Its an exclusive club on campus where Albert Einstein used to spread his genius with other smart people.
The wait list is atrocious.
This surprises Amy since shes already arranged for them to take a tour.
Its unfortunate timing that Leonard and Penny just happen to be eating lunch at The Athenaeum that afternoon.
Cover your eyes, dead scientists.
Sheldon is about to throw down.
It seems that Leonard has been a member for years.
The Athenaeum is his own private sanctuary away from his former whacked-out roommate.
She hears the worst thing ever on the other end of the line: Your date is booked.
Kripke does not budge.
He wants his wild and crazy birthday party with the dead scientists looking on.
Feeling somewhat guilty, Leonard intervenes and implores Barry to change his mind.
Since Barry is not a nice human being, Leonard breaks him by doing all of Barrys dirty work.
Scrubbing a few barrels of radioactive waste is just the ticket to secure The Athenaeum.
Sheldon joins Leonard, and together they knock out the grunt work.
Amy decides to have her wedding at the planetarium.
Or at least look into the whole Mars thing.
Howard sets out to prove to Bernadette that he is the obvious choice.
Howard fails miserably and calls Raj to help him negotiate bath time, dinner time, and bed time.
My money is on Raj.
Theoretical Laughter
SHELDON: I said some unprofessional things about Barrys work.
I may have used the S word.AMY: Sub-par?SHELDON: Im not proud of it.
The longer it went on, the funnier it got.
RAJ: He only drinks milk.
Where are the colors coming from?
