Talk:The Apartment Building/@comment-70.79.54.243-20120921021554

In "References", #3, it states that there's a third apartment across the elevator on the 4th floor. The following screenshots show that there are only two apartments: in the top photo you can see Penny's apartment's door, on the bottom photo you can see Leonard's apartment's door, and there is that garbage can between them.
