The Jim Halpert Explains meme is a popular reaction template featuring John Krasinski’s character from the hit sitcom 'The Office.' The image comes from the Season 6 episode 'The Delivery,' where Jim uses a whiteboard to explain a logic-based plan to his coworkers. Online, the whiteboard is typically edited to feature facts, controversial opinions, or humorous explanations. Since rising to fame on Reddit and Twitter around 2019, it has become a staple of the 'presentation meme' genre, utilized by users to simplify complex ideas or highlight obvious truths in a sarcastic manner.
