During Audrey's outburst of anger in Brian's den, she pushes papers and items off of Brian's desk. The computer keyboard remains off-set but is one of the few items in the shot. As Jerry approaches Audrey to comfort her, a drafter's ruler (architect scale) is now on the desktop and no keyboard is noticeable.
When Jerry is filling out his examination; he starts with his first name and then his last. However, on top of the examination, it clearly shows; Last, First, M.I. which is standard on most forms. Additionally, he uses his nickname as a first name when he should be using his legal name which is Jerald. This is likely a part of the character development to show he still has attention and focusing issues due to his addiction.
