The Big Bang Theory: 15 Insane Details You Definitely Missed
9. The Apartment Building Has More Mailboxes Than Apartments
This is a particularly exceptional piece of sleuthing from users of The Big Bang Theory's IMDb page.
Whenever the front lobby to the apartment complex is shown, there are sixteen mailboxes on display, indicating sixteen apartments in the complex. This is far from the correct number, however, as there are actually only eight apartments in the building, for a total of two apartments per floor. There are no apartments on the first floor - where the mailboxes are - and two on each of the floors ascended by the gang before they reach their own landing. Above them is only one further floor that encompasses the final two apartments.
It's well documented that there are no hidden apartments on each floor either, as the purported 'missing' fourth wall has long been established as the outer wall, the one where Sheldon can open a window to create that illustrious cross-breeze he so desperately craves in the apartment.
