During Toby's going away party, Andy gets on stage to propose to Angela. He says he can't think of a better time, with the music playing, all his friends around, and his parents being there. The camera pans to his mother and father, who are two completely different actors than who play his parents in later episodes in following seasons. In this shot we see his parents seem very happy to be there, and happy to be given an introduction by Andy from the stage. His 'real' parents as we know them later on are ashamed of Andy and his antics, and would not have reacted the same way.
While on the phone with Pam just after the work day ends, Jim asks her how many words per minute the average person types. Pam replies that she types 90 WPM, and guesses the average person types 70 WPM. Jim replies that he types 65 WPM, which Pam calls "respectable". The average person types between 38 and 40 WPM, what translates into between 190 and 200 characters per minute (CPM).
