Greg Heffley Yearbook Photo or Greg Heffley Before And After is a reaction image used to mock supposed transformations or glowups in which someone appears to have barely changed their appearance over time. The image is commonly posted in TikTok comments, particularly on videos showcasing before-and-after transformations.
The meme features two school-portrait-style images of Greg Heffley, played by Zachary Gordon in the 2010 live-action film Diary of a Wimpy Kid, based on the book of the same name. The awkward school-photo aesthetic and Gordon’s appearance in the film became the basis for the comparison, with users typically implying that the person in question looks essentially the same.
