In the Family Guy episode,"The Story on Page One", the Griffins visit Brown University near the beginning. When Chris, Stewie, and Brian visit the Physics department, they go into a chemistry lab. The doorknob to the lab is on the left side of the door to start. When Stewie is inside the classroom, the doorknob as viewed on the inside of the room, is on the right side of the door. This is where the doorknob should be. But, when Stewie is pushed out of the lab by the scientist, it appears that the doorknob on the outside is now on the right side instead of the left.
