Who Is Your Favorite Substitute?

My favorite substitute teacher is Mrs. Waters. She thinks she can teach students the subject of Chemistry when she got a degree in English. I came into class this morning and saw Mrs. Waters's smiling face. I had to have a double take because never in my life would I think Mrs. Waters would ever teach us Chemistry. Luckily, Mrs. Waters just stayed behind her desk and stopped everybody from attacking each other. Mrs. Waters is DEFINITELY my FAVORITE substitute!
