Calvin and Hobbes by Bill Watterson for March 31, 1989
Calvin: Psst...Susie! Help me think up scientific names of my bugs while this teacher's not looking. Susie: Shhh! We're not supposed to talk in class. Do it yourself. Miss Wormwood: Having a pleasant conversation, Miss Derkins? Susie: Eeep! Miss Wormwood: Perhaps you'd like to sit up front, so you won't distract Calvin anymore. Calvin: Oh. I tried to get her to be quiet, but you know how girls are.
