Calvin and Hobbes strip, but edited:
(dad walks into frame) dad: "Using a file format? lemme show you something interesting"
dad: "the two types of file format are .txt and .zip. All file formats fall into these two categories. json? txt. docx? zip"
calvin: "...yeah"
dad: "xml? txt. apk? zip."
dad: "despite containing code, which is usually text, .jar files are .zip"
(the final panel is calvin unable to sleep with the new knowledge he's been given)
